I have a module that saves a copy of the postdata in an input filter. Here is how it works: In the ap_hook_fixups function, I check to see if I am interested in this request (examine url). If yes, I then check if r->method_number == M_POST. If yes, then I add my input filter function to capture the postdata.
All worked fine until someone did this:
DirectoryIndex index.php index.php3 index.html index.htm
Now, load the above page with http://localhost/test/ (NOTE, without index.htm), and then sumbit the form. By the time I decided if I should add my input filter for index.htm, the test r->method_number == M_POST is false (it is a M_GET).
Some debugging showed that the "referer" header is not null in this case, so I modified the test from
r->method_number == M_POST
r->method_number == M_POST || apr_table_get(r->headers_in, "Referer")
and in my input filter, I check to see if the 1st bucket is EOS before saving a copy of the postdata (because a non-null referer does not mean it is really a POST request.
Is this the right way? I would like it to work on apaceh 2.*
