Haproxy route and rewrite based on URI path

Question

I am trying to setup an Haproxy to load balance requests on a few backends identified by the uri path. For example:

https://www.example.com/v1/catalog

Answer 1

If I understand you correctly, replace the example below:

reqrep ^([^\ ]\*)\ /([-.0-9A-Za-z]\*)/([a-zA-Z]\*)/(.\*)  \1\ /\3-\2/\4

reqrep search string [{if | unless} cond]

You have no spaces.
