Check your http proxy settings.  You need to have it configured.  Check 
your apache error_log for errors.

that's my code:

*static int my_module_handler (request_rec *r) {
 char *url = apr_pstrdup(r-pool,http:\\10.12.23.5\irj\test);
r-filename = apr_pstrcat(r-pool, proxy:, url, NULL);
return 1;
}

static void **my_module**_hooks(apr_pool_t *pool){
ap_hook_handler(**my_module**_handler, NULL, NULL, APR_HOOK_FIRST);
   }

module AP_MODULE_DECLARE_DATA **my_module**_module = {
STANDARD20_MODULE_STUFF,
NULL,
NULL,
auth_chorus_config,
NULL,
**my_module**_cmds,
**my_module**_hooks
};*

Thanks

I have the following error:

not

I think because the external server is not on the same site..I read the
paragraph 6.3 Diverting a Request: The internal redirect ...I think
  

there is


no external redirect for http requests...
Any suggestion please??

  

That error and assumption are correct.  As Ray stated, the
ap_sub_req_lookup_uri only works if the URI is on the local server's
apache.  (It is a URI vs. URL concept - the URI does not include the
http://servername piece of the URL.)

Instead, try a simple :

r-filename = apr_pstrcat(r-pool, proxy:, url, NULL);
return 1;

(this example was stolen from mod_rewrite, which was the only core
module that I was aware of that included a send to proxy command).
Just set the URL to what the client would have been grabbing if it was
redirected to the right page.  For example, if the client is trying to
get the page http://corvette.sharktooth.org/status.html , the resulting
line would be :

url = apr_pstrdup(r-pool,http://corvette.sharktooth.org/status.html;);
r-filename = apr_pstrcat(r-pool, proxy:, url, NULL);
return 1;

(this could also be shortened - what the three lines do are 1) get/set
the URL, which should be set in your case already, 2) preface the URL
with proxy:, which is an indicator to proxy the request elsewhere, and
3) allow apache to handle the rest of the request).

Try it and let us know if that works for you.

Re: [Module Dev] Sending http request

2008-01-16 Thread Ray Morris 
  If the URL is on the same site, you can
use a subrequest.  Below is an example of
doing a subrequest. ap_run_sub_req only needs
to be run if you need the body of the response.
The headers can be accessed after calling
ap_sub_req_lookup_uri.  Authentication is
skipped for subrequests by default, so if you
need to run autentication call ap_get_basic_auth_pw
as below.  The copying of the authentication
and host headers probably isn't needed, but 
was something I put in before discovering the
need to call ap_get_basic_auth_pw.  I'm no 
expert - I only know what I read in Nick's
fabulous Apache modules book. :) 

subr = ap_sub_req_lookup_uri(r-uri, r, NULL);
apr_table_set( subr-headers_in, Authorization,
apr_table_get(r-headers_in, Authorization) );
apr_table_set( subr-headers_in, Host, apr_table_get(r-headers_in,
Host) );
ap_get_basic_auth_pw(subr, sent_pw);
ap_log_rerror( APLOG_MARK, APLOG_ERR, 0, r, sub request status: %i,
subr-status );
ap_run_sub_req(subr);
