What you can to support is If-Modified-Since, which is used both by clients and Squid to send cache validations. Requires your CGI to return a Last-Modified and to know how to compare current status to the If-Modified-Since header when getting a request.. Which this in place it will be all automatic.. (assuming your CGI is smart to skip the CPU intensive stuff if If-Modified-Since indicates the previous response is still fresh). Regards Henrik
