Subject Re: Doing a subrequest with ap_run_sub_req
Date Thu, 06 May 2010 14:40:14 GMT
I wanted to do something similar, but the Apache 2 APIs require a
request_rec* in the lookup_uri method.  Tracing the code in request.c, it
uses the passed in request_rec* in make_sub_request.

The example Joe provided won't compile, and the request_rec can't be NULL
otherwise the code will segfault.  Any other ways to do this?
