Greetings AEM humans,
I am trying to test caching on Dispatcher 4.2.2 using the Apache Dispatcher module 2.2.
This guide:
Configuring Dispatcher - docs.adobe.com
Recommends sending the header "X-Dispatcher-Info" to the dispatcher, so that it will return the response header "X-Cache-Info" with the cache info about the page from dispatcher, but we can't get that to work!
Does anyone have any idea how we can get the dispatcher to return the cache info using this header? Here is a sample CURL request, we used TRUE as the docs didn't mention what payload this should be. If we don't send a value it drops the header...
$ curl -v -I --header "X-Dispatcher-Info: TRUE" http://WEBSITEURL/
* Trying 192.168.X.X..
* TCP_NODELAY set
* Connected to WEBSITEURL (192.168.X.X) port 80 (#0)
> HEAD / HTTP/1.1
> Host: WEBSITEURL
> User-Agent: curl/7.51.0
> Accept: */*
> X-Dispatcher-Info: TRUE
>

Hi,
the value of this header doesn't care, the dispatcher just checks for its existence.

You have to enable this functionality first; add a statement '/info "1"' to your farm.
/farms
/myfarm
/info "1"
Hi Jörg,
Thank you for the reply.
We enabled this in our farm, but the X-Dispatcher-Info header is dropped if it doesn't have a value. There is no value documented in the docs.
What value do we need to send through? Like:
X-Dispatcher-Info: true
X-Dispatcher-Info: 1
X-Dispatcher-Info: value
Thanks in advance!
