Keepalive and Rewrite rules in Apache 2.2

[Kiran saligrama <kiransk@xxxxxxxxx>]

Hi

We have been using Rewrite rules with Apache 2.0 to expose multiple back-end servers. We have had very good success and when we upgraded to Apache 2.2, the Rewrite connections do not honor keepalive directive anymore. The documentation does say that by default keepalive is not used and when we started using Proxy directives instead of rewrite rules, keepalive behavior is more on the expected lines.

When I looked at mod_proxy source code this default behavior seems something that changed in 2.2. Can someone confirm whether this is indeed the case and any rational for changing the default behavior would be very beneficial for me.

Thanks
Kiran
