-=head1 NAME
-
-Catalyst::Plugin::Static::Simple - Make serving static pages painless.
-
-=head1 SYNOPSIS
-
- use Catalyst;
- MyApp->setup( qw/Static::Simple/ );
-
-=head1 DESCRIPTION
-
-The Static::Simple plugin is designed to make serving static content in your
-application during development quick and easy, without requiring a single
-line of code from you.
-
-It will detect static files used in your application by looking for file
-extensions in the URI. By default, you can simply load this plugin and it
-will immediately begin serving your static files with the correct MIME type.
-The light-weight MIME::Types module is used to map file extensions to
-IANA-registered MIME types.
-
-Note that actions mapped to paths using periods (.) will still operate
-properly.
-
-You may further tweak the operation by adding configuration options, described
-below.
-
-=head1 ADVANCED CONFIGURATION
-
-Configuration is completely optional and is specified within MyApp->config->{static}.
-If you use any of these options, the module will probably feel less "simple" to you!
-
-=over 4
-
-=item Forcing directories into static mode
-
-Define a list of top-level directories beneath your 'root' directory that
-should always be served in static mode. Regular expressions may be
-specified using qr//.
-
- MyApp->config->{static}->{dirs} = [
- 'static',
- qr/^(images|css)/,
- ];
-
-=item Including additional directories (experimental!)
-
-You may specify a list of directories in which to search for your static files. The
-directories will be searched in order and will return the first file found. Note that
-your root directory is B<not> automatically added to the search path when
-you specify an include_path. You should use MyApp->config->{root} to add it.
-
- MyApp->config->{static}->{include_path} = [
- '/path/to/overlay',
- \&incpath_generator,
- MyApp->config->{root}
- ];
-
-With the above setting, a request for the file /images/logo.jpg will search for the
-following files, returning the first one found:
-
- /path/to/overlay/images/logo.jpg
- /dynamic/path/images/logo.jpg
- /your/app/home/root/images/logo.jpg
-
-The include path can contain a subroutine reference to dynamically return a list of
-available directories. This method will receive the $c object as a parameter and
-should return a reference to a list of directories. Errors can be reported using
-die(). This method will be called every time a file is requested that appears to
-be a static file (i.e. it has an extension).
-
-For example:
-
- sub incpath_generator {
- my $c = shift;
-
- if ( $c->session->{customer_dir} ) {
- return [ $c->session->{customer_dir} ];
- } else {
- die "No customer dir defined.";
- }
- }
-
-=item Custom MIME types
-
-To override or add to the default MIME types set by the MIME::Types module,
-you may enter your own extension to MIME type mapping.
-
- MyApp->config->{static}->{mime_types} = {
- jpg => 'image/jpg',
- png => 'image/png',
- };
-
-=item Apache integration and performance
-
-Optionally, when running under mod_perl, Static::Simple can return DECLINED
-on static files to allow Apache to serve the file. A check is first done to
-make sure that Apache's DocumentRoot matches your Catalyst root, and that you
-are not using any custom MIME types or multiple roots. To enable the Apache
-support, you can set the following option.
-
- MyApp->config->{static}->{use_apache} = 1;
-
-By default this option is disabled because after several benchmarks it
-appears that just serving the file from Catalyst is the better option. On a 3K
-file, Catalyst appears to be around 25% faster, and is 42% faster on a 10K file.
-My benchmarking was done using the following 'siege' command, so other
-benchmarks would be welcome!
-
- siege -u http://server/static/css/10K.css -b -t 1M -c 1
-
-For best static performance, you should still serve your static files directly
-from Apache by defining a Location block similar to the following:
-
- <Location /static>
- SetHandler default-handler
- </Location>
-
-=item Debugging information
-
-Enable additional debugging information printed in the Catalyst log. This
-is automatically enabled when running Catalyst in -Debug mode.
-
- MyApp->config->{static}->{debug} = 1;

+=head1 NAME
+
+Catalyst::Plugin::Static::Simple - Make serving static pages painless.
+
+=head1 SYNOPSIS
+
+ use Catalyst;
+ MyApp->setup( qw/Static::Simple/ );
+ # that's it; static content is automatically served by
+ # Catalyst, though you can configure things or bypass
+ # Catalyst entirely in a production environment
+
+=head1 DESCRIPTION
+
+The Static::Simple plugin is designed to make serving static content in
+your application during development quick and easy, without requiring a
+single line of code from you.
+
+This plugin detects static files by looking at the file extension in the
+URL (such as B<.css> or B<.png> or B<.js>). The plugin uses the
+lightweight L<MIME::Types> module to map file extensions to
+IANA-registered MIME types, and will serve your static files with the
+correct MIME type directly to the browser, without being processed
+through Catalyst.
+
+Note that actions mapped to paths using periods (.) will still operate
+properly.
+
+Though Static::Simple is designed to work out-of-the-box, you can tweak
+the operation by adding various configuration options. In a production
+environment, you will probably want to use your webserver to deliver
+static content; for an example see L<USING WITH APACHE>, below.
+
+=head1 DEFAULT BEHAVIOR
+
+By default, Static::Simple will deliver all files having extensions
+(that is, bits of text following a period (C<.>)), I<except> files
+having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
+C<xhtml>. These files, and all files without extensions, will be
+processed through Catalyst. If L<MIME::Types> doesn't recognize an
+extension, it will be served as C<text/plain>.
+
+To restate: files having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>,
+and C<xhtml> I<will not> be served statically by default, they will be
+processed by Catalyst. Thus if you want to use C<.html> files from
+within a Catalyst app as static files, you need to change the
+configuration of Static::Simple. Note also that files having any other
+extension I<will> be served statically, so if you're using any other
+extension for template files, you should also change the configuration.
+
+Logging of static files is turned off by default.
+
+=head1 ADVANCED CONFIGURATION
+
+Configuration is completely optional and is specified within
+C<MyApp-E<gt>config-E<gt>{static}>. If you use any of these options,
+this module will probably feel less "simple" to you!
+
+=head2 Enabling request logging
+
+Since Catalyst 5.50, logging of static requests is turned off by
+default; static requests tend to clutter the log output and rarely
+reveal anything useful. However, if you want to enable logging of static
+requests, you can do so by setting
+C<MyApp-E<gt>config-E<gt>{static}-E<gt>{logging}> to 1.
+
+=head2 Forcing directories into static mode
+
+Define a list of top-level directories beneath your 'root' directory
+that should always be served in static mode. Regular expressions may be
+specified using C<qr//>.
+
+ MyApp->config->{static}->{dirs} = [
+ 'static',
+ qr/^(images|css)/,
+ ];
+
+=head2 Including additional directories
+
+You may specify a list of directories in which to search for your static
+files. The directories will be searched in order and will return the
+first file found. Note that your root directory is B<not> automatically
+added to the search path when you specify an C<include_path>. You should
+use C<MyApp-E<gt>config-E<gt>{root}> to add it.
+
+ MyApp->config->{static}->{include_path} = [
+ '/path/to/overlay',
+ \&incpath_generator,
+ MyApp->config->{root}
+ ];
+
+With the above setting, a request for the file C</images/logo.jpg> will search
+for the following files, returning the first one found:
+
+ /path/to/overlay/images/logo.jpg
+ /dynamic/path/images/logo.jpg
+ /your/app/home/root/images/logo.jpg
- $path = $c->_static_file;
- my $stat = stat( $path );
-
- # the below code all from C::P::Static
- if ( $c->req->headers->if_modified_since ) {
- if ( $c->req->headers->if_modified_since == $stat->mtime ) {
- $c->res->status( 304 ); # Not Modified
- $c->res->headers->remove_content_headers;
- return 1;
+The include path can contain a subroutine reference to dynamically return a
+list of available directories. This method will receive the C<$c> object as a
+parameter and should return a reference to a list of directories. Errors can
+be reported using C<die()>. This method will be called every time a file is
+requested that appears to be a static file (i.e. it has an extension).
+
+For example:
+
+ sub incpath_generator {
+ my $c = shift;
+
+ if ( $c->session->{customer_dir} ) {
+ return [ $c->session->{customer_dir} ];
+ } else {
+ die "No customer dir defined.";
}
}
+
+=head2 Ignoring certain types of files
- my $content = read_file( $path );
- $c->res->headers->content_type( $type );
- $c->res->headers->content_length( $stat->size );
- $c->res->headers->last_modified( $stat->mtime );
- $c->res->output( $content );
- return 1;
-}
+There are some file types you may not wish to serve as static files.
+Most important in this category are your raw template files. By
+default, files with the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
+C<xhtml> will be ignored by Static::Simple in the interest of security.
+If you wish to define your own extensions to ignore, use the
+C<ignore_extensions> option:
-sub _debug_msg {
- my ( $c, $msg ) = @_;
-
- $c->_debug_message( [] ) unless ( $c->_debug_message );
+ MyApp->config->{static}->{ignore_extensions}
+ = [ qw/html asp php/ ];
- push @{ $c->_debug_message }, $msg if $msg;
+=head2 Ignoring entire directories
+
+To prevent an entire directory from being served statically, you can use
+the C<ignore_dirs> option. This option contains a list of relative
+directory paths to ignore. If using C<include_path>, the path will be
+checked against every included path.
+
+ MyApp->config->{static}->{ignore_dirs} = [ qw/tmpl css/ ];
- return $c->_debug_message;
-}
+For example, if combined with the above C<include_path> setting, this
+C<ignore_dirs> value will ignore the following directories if they exist:
+
+ /path/to/overlay/tmpl
+ /path/to/overlay/css
+ /dynamic/path/tmpl
+ /dynamic/path/css
+ /your/app/home/root/tmpl
+ /your/app/home/root/css
+
+=head2 Custom MIME types
+
+To override or add to the default MIME types set by the L<MIME::Types>
+module, you may enter your own extension to MIME type mapping.
+
+ MyApp->config->{static}->{mime_types} = {
+ jpg => 'image/jpg',
+ png => 'image/png',
+ };
+
+=head2 Compatibility with other plugins
+
+Since version 0.12, Static::Simple plays nice with other plugins. It no
+longer short-circuits the C<prepare_action> stage as it was causing too
+many compatibility issues with other plugins.
+
+=head2 Debugging information
+
+Enable additional debugging information printed in the Catalyst log. This
+is automatically enabled when running Catalyst in -Debug mode.
+
+ MyApp->config->{static}->{debug} = 1;
+=head1 USING WITH APACHE
+
+While Static::Simple will work just fine serving files through Catalyst in
+mod_perl, for increased performance, you may wish to have Apache handle the
+serving of your static files. To do this, simply use a dedicated directory
+for your static files and configure an Apache Location block for that
+directory. This approach is recommended for production installations.
+
+ <Location /static>
+ SetHandler default-handler
+ </Location>
+
+Using this approach Apache will bypass any handling of these directories
+through Catalyst. You can leave Static::Simple as part of your
+application, and it will continue to function on a development server,
+or using Catalyst's built-in server.
+
+=head1 PUBLIC METHODS
+
+=head2 serve_static_file $file_path
+
+Will serve the file located in $file_path statically. This is useful when
+you need to autogenerate them if they don't exist, or they are stored in a model.
+
+ package MyApp::Controller::User;
+
+ sub curr_user_thumb : PathPart("my_thumbnail.png") {
+ my ( $self, $c ) = @_;
+ my $file_path = $c->user->picture_thumbnail_path;
+ $c->serve_static_file($file_path);
+ }
+
+=head1 INTERNAL EXTENDED METHODS
+
+Static::Simple extends the following steps in the Catalyst process.
+
+=head2 prepare_action
+
+C<prepare_action> is used to first check if the request path is a static
+file. If so, we skip all other C<prepare_action> steps to improve
+performance.
+
+=head2 dispatch
+
+C<dispatch> takes the file found during C<prepare_action> and writes it
+to the output.
+
+=head2 finalize
+
+C<finalize> serves up final header information and displays any log
+messages.
+
+=head2 setup
+
+C<setup> initializes all default values.
