• Filtering mode:
  • Local Vpn
• Device:
  • Oneplus 7t
• Operating system and version:
  • Android 11
• Root access:
  • Yes

Expected Behavior

$removeparam should remove given parameters from specified domain URL

Actual Behavior

NO changes in the URL is observed in https post reqs

Screenshots

So the ookla speedtest app sends sensitive data line IMEI no. device fingerprint, phone tower area code etc to their servers. I want to block this by stripping off the tracking parameters from the URL. The rule I created is this:- ||speedtest.net^$removeparam=/^(fingerprint|build_id|imei)=/ But it doesn't work. The URL is unmodified as displayed in filtering logs. @ameshkov said that adguard can only modify document type https data in POST reqs, and will be improved later

Request to please fix this as soon as possible

Additional Information

Text me as "Ayan_c99" in telegram for screenshots. Although @ameshkov has all the info

Applying $removeparam to POST requests is technically possible, but might be dangerous.

This issue should be moved to the CoreLibs repo and triaged there.
