How to make HAProxy path use backend (including links/scripts)?

jonathan.young

Hi, I have setup HAProxy so that https://abc.xyz.com/test points to backend http://def.xyz.com.

acl                     small   var(txn.txnpath) -m beg -i /test
http-request set-path /  if  small

At the root level this works but links/images/scripts fail. Do I need to set something up on the backend to add '/test' into the links? If so, how do I do it?

Many Thanks

What do the requests at the backend look like? If the /test is missed you have to configure HAproxy to add it in the backend settings.

@viragomann Thanks for replying. The logs show:

Mar 1 21:21:47 pfsense haproxy[75602]: 10.1.1.50:49456 [01/Mar/2023:21:21:47.545] test~ test/<NOSRV> -1/-1/-1/-1/0 503 565 - - SC-- 4/4/0/0/0 0/0 "GET /50021701/images/image1_hp.gif HTTP/1.1"

which is a blank icon. So I think I need something on the backend that will change the GET to:

"GET /test/50021701/images/image1_hp.gif HTTP/1.1"

but I am at a bit of loss how to write the script or where to put it exactly.

Just to be clear. Backend website def.xyz.com/index.html contains an image at /50021701/images/image1_hp.gif which I want to be displayed (along with everything else in the page) when I navigate to https://abc.xyz.com/test

Thanks for the help.

You can do something like this to insert the /test directory:

In the backend add an ACL:
name: notest
path starts with
"Not" checked
value: /test/

action:
http-request set-path
fmt: /test/%[path]
acl: notest
