HAProxy List,
I am attempting to have traffic route to HAProxy using different root contexts
in the path. I would like to keep that root context in the users browser and
just concatenate an application's path changes as a suffix. So, for example:
1. User enters /testensc in there browser.
2. HAProxy scans for testensc and uses an ACL to route the traffic to a
specific back-end
3. Uses reqrep and/or rsprep to properly modify the request for server
purposes, but the user is never made aware of this in the browser
4. Opening page user sees has URL /testensc/login.apsx (for
example)
5. All subsequent pages after logging in maintain the root context.
I have not been able to get #4 and #5 to work. If I need to modify the
application level to make this work that is fine, but was hoping HAProxy could
somehow handle this for me.
Below are config file snippets from each section. I originally tried just the
reqrep line but also tried rsprep as well upon suggestion. Neither seems to
make a difference in action. Right now, for debugging purposes, the web and
default servers are similar but eventually the default will be written to
handle any non-standard traffic. I included it also so the attached log snippet
makes sense. It looks like initial request gets routed to the web server
instance (web_ensc), but subsequent requests are going to the default server
(default_ensc), since the URL no longer seems to contain the "testensc" string.
Any suggestions on things to try?
Thanks,
Zack
