Problem with path strip and prepend

[lastcmaster]

We can not get fabio to strip the only element in the URL, se example:
`
Target:
http://k8swork01.hi5.ismobile.com:8083/optimizer/optservlet

=================
Problem setup:

Consul tag:
urlprefix-optimizer.cloud.ismobile.com/sweden strip=/sweden prepend=/optimizer/optservlet

Extenal call:
https://optimizer.cloud.ismobile.com/sweden?sync&timeout=20

Expected:
POST /optimizer/optservlet?sync&timeout=20 HTTP/1.1
Host: optimizer.cloud.ismobile.com

Actual:
POST /optimizer/optservlet/sweden?sync&timeout=20 HTTP/1.1
Host: optimizer.cloud.ismobile.com

=================
Working setup:

Consul tag:
urlprefix-optimizer.cloud.ismobile.com/sweden strip=/sweden

Expected:
POST /optimizer/optservlet?sync&timeout=20 HTTP/1.1
Host: optimizer.cloud.ismobile.com

One thing to look at in the fabio logs is a line like:

+ route add optimizer optimizer.cloud.ismobile.com/sweden http://optimizer.cloud.ismobile.com/ opts "strip=/sweden prepend=/optimizer/optservlet"

this will test if the urlprefix- is getting parsed properly.

You can also test the functionality manually by adding lines in the Overrides of the UI.

I've tried to reproduce the error but not succeeded.

another way to check the routing table is via the API.

$ curl -s http://fabio.service.consul:9998/api/routes | jq 'map(select(.service == "fake"))'
[
  {
    "cmd": "route add",
    "dst": "http://10.0.0.23:20869/",
    "host": "fake.service.consul",
    "opts": "strip=/sweden prepend=/optimizer/optservlet",
    "path": "/sweden",
    "pct99": 0,
    "rate1": 0,
    "service": "fake",
    "src": "fake.service.consul/sweden",
    "weight": 1
  }
]
