declarativeNetRequest regexFilter

[Browser Extenstion]

I want to create a regular expression that will match all subdomains except admin.example.com.

So, the regex is:
^(https?:\/\/)?((?!admin\.example\.com).)*example\.com

It works as expected.

Now I want to convert the regex to use in regexFilter:
^(https?://)?((?!admin\\.example\\.com).)*example\\.com

If I insert this expression, I get an error.
In this regard, my question is: does declarativeNetRequest support such a regex?
How should I modify the expression?

The API uses RE2 syntax, so no, negative lookahead/lookbehind is not supported.

See https://github.com/google/re2/wiki/Syntax

Try adding another rule for the admin domain with a bigger "id" and "type":"allow" or "allowAllRequests"

Thanks! Works!
