Redirection in proxy_http.c

[Naaman Musawwir <na...@fourthhousesecurity.com>]

Hi,

How can I redirect the request to some URL in proxy_http.c code. I tried to use an internal redirect as follows:

ap_internal_redirect("http://www.cnn.com", r);

It gives the following error:

proxy: Max-Forwards has reached zero - proxy loop? returned by http://www.cnn.com.

Any ideas? Also, what if I want to do a formal redirect instead of internal redirect?

Thanks,
Naaman Musawwir.

Thanks, I have looked at that and used the following code to redirect, but
that does not work properly. Only a sub-request gets redirected, but not the
main request. Also this code is called many times when a page is loaded. How
can I stop that? OR should I write this code somewhere else?

if(mycheck) {
        r->proxyreq=PROXYREQ_NONE;
        ap_log_error(APLOG_MARK, APLOG_INFO, 0, r->server, "%s",
"************** Redirecting");
        ap_internal_redirect("http://test.fhs.com/httpa/index.html", r);
        return OK;
}

I used this in the function ap_proxy_http_handler() in proxy_http.c.

Take a look at function proxy_trans() in modules/proxy/mod_proxy.c.

Hello,

Right. In fact, I want to intercept the request in between and want to
redirect conditionally to somewhere else instead of where redirected by
ProxyPass.

BTW where is ProxyPass implemented? I am kind of novice in Apache code :)

are you talking about the same thing that ProxyPass does?

if so, see how ProxyPass is implemented :)
