I'm having a problem whereby I can't access POST CGI variables when using an output filter (PerlOutputFilterHandler) alongside mod_proxy. Parameters on the URL (GET) work just fine, its just the POST variables that are missing.
My setup is that I'm using a mod_proxy reverse proxy to fetch some remote content, then doing some analysis on the content using an output filter. I suspect this has something to do with mod_proxy consuming the request data - i.e., once the data of the HTTP request is read, its gone.... (http://httpd.apache.org/apreq/Apache-Request.html#instance). Either way, I need some way to be able to retrieve the POST parameters in the output filter. If I install the following sample OUTPUT filter (see example httpd.conf below), the HTTP content itself is proxied ok, but the APR table scan ($CgiArgsRef->do) doesn't find any of the POST'ed variables. sub handler { # (filter) my $f = shift; my $r = $f->r; if ( ! $r->notes('not_first_bucket') ) { $r->notes->set('not_first_bucket' => 1); my $ApReq = Apache::Request->new($r); my $CgiArgsRef = $ApReq->param; # log CGI variables for debug... $CgiArgsRef->do( sub { $r->log_error("CGI parameter: '" . $_[0] . "' = '" . $_[1] . "'"); return 1; }); ) return Apache::DECLINED; } And if I install this as an INPUT filter, I *do* actually get the POST data logged, but then I wind up with a proxy error 502 -- something gets munged in the request and it doesn't get to the back end server correctly. The platform: Apache 2.0.49 mod_perl-1.99_14 libapreq2-2.03-dev perl v5.8.2 Linux kernel 2.4.21 ...and a snippet of my httpd.conf: ProxyRequests Off ProxyPass / http://remotesite ProxyPassReverse / http://remotesite PerlOutputFilterHandler +MyFilter # PerlInputFilterHandler +MyFilter TIA for any help, Eric -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
