LWIP_HTTPD_CGI_SSI macro

Set this to 1 to support CGI (new style). This new style CGI support works by calling a global function (tCGIHandler ) for all URLs that are found. fs_open is called first and the URL can not be written by the CGI handler. Instead, this handler gets passed the http file state, an object where it can store information derived from the CGI URL or parameters. This file state is later passed to SSI, so the SSI code can return data depending on CGI input. Use this CGI handler if you want CGI information passed on to SSI.
