[users@httpd] Re: How to use ap_parse_form_data and keep request body?

[Matt Hauck <ma...@gmail.com>]

So, I've been looking into how to do this possibly by dynamically enabling
the KeptBodySize. I can't seem to use this directive directly in my config
because the URLs I am working with get ProxyPass'ed to a different backend,
and do not correspond to any `Directory` element, as KeptBodySize only
appears to be applicable to Directory contexts...

The following seems like it should work:

static my_request_insert_filter(request_rec *req) {
   if (is_login_request(req)) {
       request_dir_conf *conf = ap_get_module_config(req->per_dir_config,
           &request_module);

       conf->keep_body = 8192;
       conf->keep_body_set = TRUE;

       apr_OFN_ap_request_insert_filter_t(req);
   }
}


However, the linker fails on "unresolved external symbol request_module".
Is this the right way to do about doing things? Is there a way to
lookup request_module
dynamically rather than a reference to it at compile time?

Help appreciated. Thanks.
