[mp2] how to redirect POST data

[prev] [thread] [next] [Date index for 2004/12/13]

Hi,

I found a similar question posted in the newsgroups
but no one seemed to have a solution.  Here's what I'm
trying to do.  I have a web page that does a POST to a
remote server.  Basiscally, I'm trying to read the
post data and if it matches a regex, I want to
redirect it.  Otherwise, I want to let the POST
continue normally (submitting to the remote server).  

At the PerlTransHandler stage, I have a handler that
reads the post data like so:

my $method = $r->method();
if ($method =~ /post/i) {
    my $content;		  
    $r->read($content,
         $r->headers_in->{'content-length'});
    if ($content =~ /some_regex/){
        # redirect
    } else {
        # continue with post
        return OK;
    }
}

I can capture the POST data and redirect the user just
fine. The problem occurs with the submitted forms that
don't match the regex.  If I just return OK, the
browser hangs (because the POST data has been reset?).
 I'll admit I'm a bit confused as to what's actually
going on here (still new to mod_perl).  I read you're
not supposed to parse the form data except at the
ContentHandler step, but since the form is submitting
to a remote host, I can't really do that.

Any ideaas?

Thanks,
Bill
