Google App Engine modules: routing second module to subdirectory - wordpress

Question

Has anyone run two different WordPress installations as separate modules inside Google App Engine?
I have the following:
/app/
- wordpress1
- wordpress2
- app.yaml
- second.yaml
- dispatch.yaml
- php.ini
Inside wordpress1 and wordpress2 are somewhat clean installations of WordPress, with some GAE helper plugins.
app.yaml contains the default module config, which redirects traffic to wordpress1 using URL handlers.
second.yaml contains the second module config (module: second) and redirects traffic to wordpress2.
In dispatch.yaml I only check for a subdir second to load the second.yaml config:
dispatch:
- url: "*/second*"
module: second
Everything is fine and dandy:
http://localhost.dev:8080 -> wordpress1/index.php
http://localhost.dev:8080/second/ -> wordpress2/index.php
But I can't seem to work out how to set the edge cases:
http://localhost.dev:8080/secondwithextra -> dispatcher error (no URL set)
http://localhost.dev:8080/second (missing trailing slash) -> same as above
I tried to add the following to second.yaml handlers:
- url: /second[^/].+/?
script: wordpress1/index.php # Reroute to `wordpress1` because not a directory match.
But that didn't really work out.
How can I make the second module accept request URI /second, /second/, /second/abc but not /secondxyz?
Having the dispatch.yaml URL glob set to */second/* breaks the slashless /second.

Answer 1

I think you could try to add both */second/* and /second in dispatch.yaml.
