you use redirection like this, you should B<not> print out a header as
well.
-One hint I can offer is that relative links may not work correctly
-when you generate a redirection to another document on your site.
-This is due to a well-intentioned optimization that some servers use.
-The solution to this is to use the full URL (including the http: part)
-of the document you are redirecting to.
+You should always use full URLs (including the http: or ftp: part) in
+redirection requests. Relative URLs will not work correctly.
You can also use named arguments:
The B<-nph> parameter, if set to a true value, will issue the correct
headers to work with a NPH (no-parse-header) script. This is important
-to use with certain servers, such as Microsoft Internet Explorer, which
+to use with certain servers, such as Microsoft IIS, which
expect all their scripts to be NPH.

It is possible for a script to receive CGI parameters in the URL as
well as in the fill-out form by creating a form that POSTs to a URL
You are free to create a custom HTML page to complain about the error,
if you wish.
+You can set up a callback that will be called whenever a file upload
+is being read during the form processing. This is much like the
+UPLOAD_HOOK facility available in Apache::Request, with the exception
+that the first argument to the callback is an Apache::Upload object,
+here it's the remote filename.

+ $q->upload_hook(\&hook,$data);

+ sub hook

+
+If using the function-oriented interface, call the CGI::upload_hook()
+method before calling param() or any other CGI functions:
+
+ CGI::upload_hook(\&hook,$data);
+
+This method is not exported by default. You will have to import it
+explicitly if you wish to use it without the CGI:: prefix.
+
If you are using CGI.pm on a Windows platform and find that binary
files get slightly larger when uploaded but that text files remain the
same, then you have forgotten to activate binary mode on the output
associative array with the attribute's name as the key and the
attribute's value as the value.

CGI.pm has limited support for HTML3's cascading style sheets (css).
To incorporate a stylesheet into your document, pass the
start_html() method a B<-style> parameter. The value of this
-parameter may be a scalar, in which case it is incorporated directly
-into a <style> section, or it may be a hash reference. In the latter
+parameter may be a scalar, in which case it is treated as the source
+URL for the stylesheet, or it may be a hash reference. In the latter
case you should provide the hash with one or more of B<-src> or
B<-code>. B<-src> points to a URL where an externally-defined
stylesheet can be found. B<-code> points to a scalar value to be
your_script.pl "name1='I am a long value'" "name2=two\ words"
+Finally, you can set the path info for the script by prefixing the first
+name/value parameter with the path followed by a question mark (?):
+
+ your_script.pl /your/path/here?name1=value1&name2=value2
