I am trying to trace a problem between mod_cgid and mod_cache. Sorry if this seems like a request for support, but this is too technical for other lists.
In 2.0.43 mod_cgid will use apr_bucket_pipe_create so that it can call ap_scan_script_header_err_brigade to remove the script headers from the output and place them into r->headers_out. ap_scan_script_header_err_brigade is just a call to ap_scan_script_header_err_core with getsfunc_BRIGADE. This function tries to act like gets(), and therefore must split the bucket after each newline. The problem is, the bucket is a pipe, and from what I can tell, you can split pipe buckets. I got this far because mod_cache won't cache the output of my CGI script. It turns out that when it reads the bucket to place the output in the cache (mod_mem_cache) the bucket contains the script headers. This cause the buffer overflow check to fail, and thus the caching to fail. Am I missing something here? I must be because the script output looks good (the body does not contain the headers), but it shows up in mod_cache. BTW, I made CACHE_IN run as AP_FTYPE_CONTENT_SET+20 so that it would run as late as possible. -- Peter Jones <jesus;unix;c++;crypto;vi;4wd;geek> [ http://pmade.org ] PGP Fingerprint: 27AD 7922 D3BC 46A3 3627 D7B4 4240 46C3 A41E 844A
