I have the following scenario :
- Apache/2.2.19 (Solaris 10 SPARC)
SetInputFilter alterxmlbody (AP_FTYPE_RESOURCE)
SetHandler weblogic-handler
First off, the [email protected] list is a better place for this, this is
the APR list.
The handler forwards requests to multiple weblogic servers
and the filter itself analyzes and/or changes the POST data
in a way that the length of the incoming request may be changed.
The question is :
What is the proper and legitimate way to deal with this situation?
Should the input filter set the new CL value in "headers_in" before
returning from the callback, or just remove it from the list?
apr_off_t length;
apr_brigade_length (bb,1,&length);
apr_table_setn(f->r->headers_in, "Content-Length", apr_off_t_toa(f->r->pool,
length));
This is definitely wrong - a filter can expect to be called multiple times, the
above code assumes you'll be called once.
or
apr_table_unset(f->r->headers_in, "Content-Length");
This is the simplest way to do it, a further filter inside httpd will put
Content-Length back if practical.
Look in the httpd source for examples on how filters handle this kind of thing.

Graham
