Ensure that Unami doesn't throw the referees into the none

Unami throws some referees to none

That's why it's not possible to get, for example, a Google Discovery traffic feed from a referrer that looks something like "android-app://google.android.googlequicksearchbox/".

Will the new expression capture this URL? android-app://com.google.andruid.googlequicksearchbox/

Why?
Let's break down the regular expression ^[\w-]+://\w+:

^[\w-]+: This part matches one or more alphanumeric characters or hyphens at the start of the string.
://: This matches the exact sequence ://.
\w+: This part expects one or more alphanumeric characters (letters, digits, or underscores) following ://.
Your URL android-app://com.google.andruid.googlequicksearchbox/ starts with android-app://, which matches the first two parts of the regex. The issue arises with the third part, which requires only alphanumeric characters after ://.

Breakdown of the URL android-app://com.google.andruid.googlequicksearchbox/:
android-app matches ^[\w-]+.
:// matches ://.
com.google.andruid.googlequicksearchbox does not match \w+ because it contains periods (.).
The dot . is not considered an alphanumeric character or an underscore, so the regular expression \w+ will not match it. Because of this, the regular expression will not return true for this URL.

Potential Fix for the Regular Expression:
If you want the regular expression to match URLs that include periods (.) after ://, you could modify it as follows:

javascript
Zkopírovat kód
/^[\w-]+://[\w.-]+/
This new regular expression:

^[\w-]+: Matches the scheme (e.g., android-app).
://: Matches the :// part.
[\w.-]+: Matches any alphanumeric characters, underscores, dots, or hyphens after ://.
With this modification, the URL android-app://com.google.andruid.googlequicksearchbox/ would be successfully matched.
