HTTP host header
A load balanced application, with 4 backend devices ,apparently does not like the vip DNS name placed in the host: part of the http header. The app developer states that the F5 needs to replace the vip DNS with the actual destinations name or IP in the http header. This is the request leaving the F5 toward the pool member.
By tricking the local WS using a hosts file edit and having DNS resolve to the specific backend host's DNS name, the service works. The 3 other backend devices were disabled for this test.
Can anyone help with a rule that will replace the Host: portion of a HTTP Header to match the name of the selected pool member?
