Path template configuration with regular expressions

[miqh]

Hello,

I went through the documentation page on routing and didn't notice any mention for using regular expressions in path template properties.

After haphazardly experimenting with different expressions for UpstreamPathTemplate, I noticed a simple expression like (.+) appeared to be able to match against input, but I couldn't figure out whether the captured group could be used in DownstreamPathTemplate. Or perhaps this was purely coincidental behaviour.

I just wanted to ask whether or not there was support for using regular expressions to capture fragments of a route. If there's any documentation I missed regarding this, please point me in the right direction.

Currently using version 12.0.1.

Thanks in advance.

This will be resolved as part of my work on #737

Currently regex will work in the path, but the capture groups cannot be sent to the downstream. After this work, this will be possible.

How does it work? Please show an example and code!

Aha! The #737 issue is closed by me. Reason: No communication.

@philproctor, that's great to hear! Thanks for the update. 🙌

Would this allow routing restrictions, so that if certain values appear in the upstream route they will go to destination 1, if others appear go to destination 2?

Defining 2 ReRoutes is fine, but I want to have something like:

myurl/customer/(Bob|Andy)/accounts go to destination 1,
myurl/customer/(Other|Any|None)/accounts go to destination 2

Thanks.

Regular expressions in templates are not supported/implemented!

No documentation at all! Not implemented!
