HAProxy reqrep not replacing string in url

We have deprecated some software which was available under http://localhost/test and is now available under http://localhost/app/testing. We are using HAProxy 1.4

Thus, I want via haproxy, to replace all urls containing /test with /app/testing/. I tried first with a redirect prefix in order to keep the query string, but /test wasn't removed from the url and had something like /app/testing/test/?id=x.

frontend all
    bind  0.0.0.0:80
    timeout client 86400000
    acl is_test path_beg /test
    redirect prefix /app/testing code 301 if is_test

Then used a reqrep, which seems to redirect to the new software, but the /test string in the url is never replaced.

frontend all
    bind  0.0.0.0:80
    timeout client 86400000
    reqrep ^([^\ :]*)\ /test[/]?(.*)  \1\ /app/testing/\2
Solution

  • Since url rewriting isn't possible with version 1.4 and we didn't want to update HAProxy, we went on using reqrep and keeping the old link as is with

    reqrep ^([^\ :]*)\ /test[/]?(.*)  \1\ /app/testing/\2
