Fixed In:

Opened: Mar 13, 2014
Severity: 2-Critical

Symptoms

When configuring a virtual with an explicit-proxy type HTTP profile, proxy requests are always handled by HTTP. In some cases it is desirable to just forward the proxy request to a pool member (configured or otherwise). This is not possible.

Impact

If another proxy is configured as a pool behind the BIG-IP system, there is no way of forwarding proxy requests to that pool.

Conditions

When receiving an HTTP proxy request, the HTTP handling will always try to resolve the hostname and forward the request to the resulting IP address.

Workaround

None.

Fix Information

A new iRule command [HTTP::proxy disable] has been added so (explicit) proxy request handing can be turned off and the request can be forwarded to another proxy.
