Upgrade from 1.8 to 2.6

Hello,

I try to upgrade from HAproxy 1.8 to 2.6 and have to replace a lot of values, as many of them are not valid anymore, and I need a bit help:

• Example 1:

reqirep ^([^:\ ]+\ +)/(/.+)/(/.+)/(/.+)/(/.+)$ \1\2\3\4\5 if { path_beg // }

This is required, to remove double // on a URL, which is from a broken upstream app, which is not under our control.

I’ve tried to use:

http-request replace-path ^([^:\ ]+\ +)/(/.+)/(/.+)/(/.+)/(/.+)$ \1\2\3\4\5 if { path_beg // }

but, I assume, that is wrong and would not work.

• Example 2:

    reqirep ^(GET|POST|HEAD)\ /iframes/(.*) \1\ /\2 if iframe
    reqirep ^(GET|POST|HEAD)\ /3dss/(.*) \1\ /\2 if 3dsecure
    reqirep ^(GET|POST|HEAD)\ /wix/(.*) \1\ /\2 if wix
    rspirep ^Location:\ (http|https)://fra-test-iframes.example.local\/(.*)   Location:\ \1://%[hdr(host)]/iframes/\2  if response-is-redirect
    rspirep ^Location:\ /(.*)   Location:\ /3dss/\1  if 3dsecure_redirect
    rspirep ^Location:\ /(.*)   Location:\ /wix/\1  if wix_redirect

this block I’ve tried to replace with:

    http-request replace-header ^(GET|POST|HEAD)\ /iframes/(.*) \1\ /\2 if iframe
    http-request replace-header ^(GET|POST|HEAD)\ /3dss/(.*) \1\ /\2 if 3dsecure
    http-request replace-header ^(GET|POST|HEAD)\ /wix/(.*) \1\ /\2 if wix
    http-request replace-header ^Location:\ (http|https)://fra-test-iframes.example.local\/(.*)   Location:\ \1://%[hdr(host)]/iframes/\2  if response-is-redirect
    http-request replace-header ^Location:\ /(.*)   Location:\ /3dss/\1  if 3dsecure_redirect
    http-request replace-header ^Location:\ /(.*)   Location:\ /wix/\1  if wix_redirect

but, HAproxy is not happy about it:

config : parsing [/opt/consul-template/data/haproxy.cfg:340] : error detected in backend 'appint' while parsing 'http-request replace-header' rule : regex '\1 /\2' is invalid (error=reference to non-existent subpattern, erroffset=1).

It would be nice, if someone can help me, to get it converted to 2.6
