I don't know the webrequest API very well... why will "*webrequest_hosted_app*"
match the request?

[robwu, 2015/09/08 17:19:48]

Because the files are served at
http://localhost:PORT/extensions/api_test/webrequest_hosted_app/index.html, the
path contains the substring "webrequest_hosted_app".

 });
