Error description
When an HTTP request is received in the HTTP Channel Framework code it does not set the Host header using the request URL before forwarding the request. If this request is forwarded to a proxy server which does not set the Host header, the request will result in a HTTP 404 error message.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * * V7.0 * **************************************************************** * PROBLEM DESCRIPTION: The Host header of the request is set * * using the remote host of the * * connection * **************************************************************** * RECOMMENDATION: * **************************************************************** When building an outbound request the HTTP Channel will add a Host header, if the header is not present, and add it using the value from the remote host. This can end up causing issues if the remote host is a proxy and the proxy is not resetting the Host header on the inbound request.
Problem conclusion
HTTP Channel was modified to use the URL host for the Host header while building an outbound request. APAR PM76226 is currently targeted for inclusion in WebSphere Application Server Fix Pack 7.0.0.29. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
