Already forwarded by dispatcher (host ip), declined.

We asked our Dispatcher expert to look at this.

What version of the dispatcher are you using? It looks to me that you ran into a limitation which tried to prevent daisy-chaining dispatcher instances, but has been removed lately.

Hi  Jörg,

Thanks for your response!

I'm using the version 4.2.3 for dispatcher and the Apache version is 2.4.29.

Files:

dispatcher-apache2.4-4.2.3.so

httpd-2.4.29.tar

The problem is this:

request.headers[Via] = "1.1 x.x.x.x (dispatcher)"

...

Already forwarded by dispatcher (x.x.x.x), declined.

The dispatcher thinks that it already had processed this request (and added a Via header), and this request is again routed through the same dispatcher instance; this means that the dispatcher detected a loop (or at least it think it does).

Can you verify that? Otherwise it would be great if you anonymize your IP addresses and server names a bit, but not just XXX'ing them :-)

Jörg

Hi  Jörg,

This is the first time I install and config Apache/dispatcher server. not sure where my problem is. hence I pasted my configuration files (httpd.conf and dispatcher.any), could you help review it?

All of the ips replaced in log and below configuration files are 10.x.x.186 server.(I hid two number of them here)

BTW, I can view the home page on Apache server normally, it displays "It works!"
