Persistent proxied connections with Apache 2.4.x?

[o haya <ohaya@xxxxxxxxx.INVALID>]

Hi,

We want to use Apache 2.4.x to proxy through to some SharePoint instances using NTLM logins.  From testing, it looks like the Apache-to-SharePoint connections need to be persistent, with "Connection: keepalive" in the request headers going from Apache-to-SharePoint.

We can do this using a directive:

ProxySet keepalive=On

inside a <Proxy [URL]> section, but we would like to do this (enable keepalive on the backend connections) on all of the backend connections.  But, if we try to put that ProxySet inside a <Proxy>, we get a startup error saying that it needs an absolute URL.

So I am wondering if there is a way to do this (make all the backend connections persistent with the "Connection: keepalive")?

Thanks,

Jim
