My understanding is that iRule
Virtual_to_enable_proxy-unaware_applications_to_make_outbound_TCP_connections_via_a_HTTP_CONNECT_METHOD
( https://devcentral.f5.com/wiki/iRules.Virtual_to_enable_proxy-unaware_applications_to_make_outbound_TCP_connections_via_a_HTTP_CONNECT_method.ashx )
will initiate a TLS tunnel thru the proxy to an SSL enabled web server.
Are there any similar methods that may be used when the target web server is non-SSL, HTTP only?
Use Case
-----------
Certificate authentication where the OCSP server can only be accessed through a proxy and the OCSP server is HTTP only.
What has been tried and does not work
------------------------------------------------
serverside { TCP::respond "POST http://ocspserver.com [append request_headers $request_payload]" }
where "POST /" was stripped from $request_headers and $request_payload is binary.
