Subject RE: [users@httpd] "Error string not specified yet: proxy: request failed to..."

Plain text please...

Obvious question: Is port 443 open on the intermediate FW?

But a quick check on google (hint, hint...) reveals this is the error you get when trying
to pass through a proxy with an HTTP method that is not supported by the proxy.

Check out this message and the faq link therein (it's about subversion but it's the same problem).
http://svn.haxx.se/dev/archive-2002-06/1638.shtml

In your case, the client must use the CONNECT method to tell the proxy to pass the requests
directly to the internal server. For this to work you need:

- mod_proxy_connect (not just mod_proxy)
- AllowCONNECT 443 (or not present - this is the default)
see http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#allowconnect for details.

Rgds,

Importance: High


I have a SunFire V210 running Solaris 9 (4/04), Apache v2.0.53 & OpenSSL v0.9.7g, configured
as a reverse-proxy for the real webserver, a Dell PE1750 running Windows Server 2003 &
IIS 6.0. In between them is a Cisco PIX firewall & a Cisco CSS. Regular http works fine,
but secure http gives me the following error:

[error] (20014)Error string not specified yet: proxy: request failed to 172.16.4.101:443 (172.16.4.101)

What the heck is going on here? Any info you can provide will be greatly appreciated.
