- This chapter explains how to code FastCGI applications in Tcl. Prior to creating a FastCGI application, you\r
- must have a FastCGI-savvy version of the Tcl interpreter. Open Market develops Tcl binaries for popular\r
- platforms and makes them available with our developer's kit.\r
- </P>\r
- <P>\r
- <A NAME="4943"></A> The FastCGI-savvy binaries are extensions of standard Tcl, and are intended to replace\r
- your existing Tcl installation. There is no need to maintain two versions of Tcl: the version that we supply\r
- will work fine when invoked from a shell or a CGI program. There are also directions in the developer's\r
- kit for how to make your own FastCGI-savvy Tcl, if you need a version for some platform that we don't\r
- supply.\r
- </P>\r
- <P>\r
- <A NAME="4221"></A> In many cases, you can convert a Tcl script from CGI to FastCGI by adding a few lines of\r
- code to an existing script. For more complex scripts, you may also need to rearrange some existing code.\r

- The first line of any Tcl script typically specifies the pathname of the Tcl interpreter itself. You must\r
- specify the pathname of a FastCGI-savvy Tcl.\r
- </P>\r
- <P>\r
- <A NAME="4226"></A> Then, you have to divide FastCGI scripts into the following two sections:\r

- <BR>\r
- <UL>\r
- <LI CLASS="c2">\r
- <A NAME="4227"></A>\r
- </LI>\r
- <LI>\r
- Initialization section, which is executed only once. <A NAME="4228"></A>\r
- </LI>\r
- <LI>\r
- Response loop section, which gets executed every time the FastCGI script gets called.\r
- </LI>\r
- </UL>\r
- <A NAME="4229"></A>\r
- <P>\r
- A response loop typically has the following format:\r
- </P>\r
- <BR>\r
- <BR>\r
-<PRE>\r
-<A NAME="4923">while {[FCGI_Accept] >= 0 } {\r
