[RESOLVED] Request for help HAPROXY redirection to subdirectory.

Tueurdragon

Hello everyone,

I allow myself to write to you, because I would need a little help.

I am having difficulty setting up HAPROXY.

Here is the context:
I have an IIS web server that hosts multiple sites in subdirectories and I would like to use HAPROXY to rewrite URLs to the subdirectories.

Example:
https://test1.test.fr --> which would actually point on the backend 192.168.1.1 to the test1 subdirectory (http://192.168.1.1/test1/)
https://test2.test.fr --> which would actually point on the same backend 192.168.1.1 to the test2 subdirectory http://192.168.1.1/test2/

Can someone nice give me some info on the settings?

Thank you very much,

Tueurdragon

Hello everyone.

After a few days of research, I managed to solve my problem.

For information, here is how to perform the operation.

In the FrontEnd part

I added the following ACLs:

ACL No. 1
Name: Domain1
Phrase: Host matches
CS: no
Note: no
Value: test1.test.fr

ACL No. 2
Name: Domain2
Phrase: Host matches
CS: no
Note: no
Value: test2.test.fr

ACL No. 3
Name: SubPath
Expression: Path matches
CS: no
Note: no
Value: /

I then added the following Actions:

Action No. 1
Action: Use Backend
Parameters: See below
Conditional acl names: Domain1
Backend: (your backend name) ex: 192.168.1.1

Action No. 2
Action: http-request set path
Parameters: See below
Condition acl names: Domain1 Subpath
fmt: /test1

Action No. 3
Action: Use Backend
Parameters: See below
Condition acl names: Domain2
Backend: (your backend name) ex: 192.168.1.1

Action No. 4
Action: http-request set path
Parameters: See below
Condition acl names: Domain1 Subpath
fmt: /test2

Have a lovely day everybody.

@tueurdragon thank you for this. I'm new to HAProxy but I'm still having issues getting everything to work and cannot figure it out. How does the 'subpath' tie into a backend or do your servers use another reverse proxy? Has anything changed in your config or would you be able to post a generic config? Mine is listed below.
