The Host header should always be sent to the backend, not doing so violates HTTP/1.1. This sounds like a bug of some kind. Regards, Graham -- smime.p7s Description: S/MIME Cryptographic Signature

A host header *is* sent to the backend, but it is the *wrong* one (the hostname of the worker I assume and not the hostname of the reverse proxy). Regards Rüdiger

-Ursprüngliche Nachricht- Von: Gregor J. Rothfuss hi, i am trying to use mod_proxy_balancer with a backend that is in turn using name-based virtual hosts. it seems that mod_proxy_balancer doesn't honor ProxyPreserveHost (both 2.2.0 and trunk), and does not send the Host: header to the backend. After a first quick view in the code on trunk I cannot see a problem there. Can you please post your config here, such that we can rule out a config problem? Furthermore could you please open a bug in bugzilla for this? This makes things easier to track and to reference. Regards Rüdiger

I can't recreate that here... Can you provide more info? On Feb 13, 2006, at 12:43 AM, Gregor J.

Re: AW: Support for ProxyPreserveHost with mod_proxy_balancer?
ProxyPassReverse / balancer://tiles_live_cluster/ This looks wrong, shouldn't this be http://reverse.proxy.host/ ? Joost

I think he needs a separate ProxyPassReverse line for *each* of the backend servers he configured in the cluster. The balancer://tiles_live_cluster/ is not used any longer once an appropriate worker has been chosen from the cluster. Regards Rüdiger
