Problem with path strip and prepend #948

Open lastcmaster opened 4 weeks ago

lastcmaster commented 4 weeks ago

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

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

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

Actual: 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.
