Glob Matcher is not working for me

[SachinMule]

I am using Glob matcher, but it does not seem to be working for me.
Below is the Fabio logs. You can see that it is adding route for /s0*and it is configured to use glob matcher.
When i access /s0/v1/call it says No route for 10.5.6.103:9999/s0/v1/call

Following is the docker command i used to start fabio:
docker run -d --name fabio --net mydockernetwork --ip 172.20.0.6 -p 9999:9999 -p 9998:9998 -v $PWD/fabio.properties:/etc/fabio/fabio.properties magiconair/fabio

Why is it not working as expected?

I believe that * will only match non / characters, as fabio is using the Path.Match function for the matcher, which like most glob implementations doesn't match the / path separator character:

https://github.com/fabiolb/fabio/blob/bc264cdc09364b888324046f2cbd659e3d4172e7/route/matcher.go#L26

Therefore /s0/v1/call won't match the glob pattern /s0*, though /s0v1call for example would.

golang/go#11862 is a semi-related discussion related to the Go Path package.

Thanks a lot for the info @snh.
