Well, first off, let me confess my ignorance of how FrontPage works. Now, I will talk about what I do know. Maybe someone with a little knowledge of FrontPage will be able to piece together why this doesn't work. mod_backhand actually plays "man-in-the-middle" wth regards to proxying HTTP requests. It takes the liberty of upgrading non-persistent HTTP sessions to persistent sessions during proxying. This allows mod_backhand to maintain open TCP/IP sessions and pipeline the HTTP requests/responses between itself and another server, while the client never knows the difference. Client -> HTTP/1.0 no keepalive -> mod_backhand -> upgrades to keepalive -> selected server -> HTTP/1.0 with keepalive -> mod_backhand -> HTTP/1.0 no keepalive -> Client. Because of this, mod_backhand must know the internals of HTTP and counts on the request and response being valid HTTP/1.0 requests... If frontpage requires a "change" to the HTTP protocol, that would completely break mod_backhand's ability to HTTP redirect the request. But, perhaps the HTTP redirection methods will work for you: http://www.backhand.org/mod_backhand/FAQ.shtml#question7 Hope this helps some :-) kstone@win.net wrote: > Has anyone tried this combination and gotten it to work successfully? > > I'm attempting to use backhand with Apacke/SuExec/FP2K extentions..
