Description

Code Suggestion

We implement what we've done with Map Local, it means, we have

BlockList Entry
BlockListService

Ping @NghiaTranUIT for the Swift Code for reference.

Block Action

1. Block & Hide Request

Select by default
If the request is blocked -> Never add it to the Flow Pool -> Never render it on the table view

2. Block & Display Request

If the request is blocked -> Generate a fake response with error = "Blocked Block List"
Add this request to the pool -> Render to the table view as normal

3. Hide, not Block

Simple never add this flow Pool -> Never display on the main table

Critical Logic

⚠️ Here is how they evaluate if the request should be blocked or not

Proxy Connect Mode

When the Request is in Proxy Connect Mode (Not SSL Proxying, not decrypted data) (Func startProxyConnection(), Tunnel.ts)
At this point, we already have the host + port
We evaluate the request with the Block Tool
If it's matched -> Close the socket immediately -> No need to wait for the body.
Make sure we clean the tunnel -> Remove from the pool if needed.

HTTP / HTTPS with SSL Proxying

When the request starts in the func startHTTPConnection()
At this point, we have the URL -> evaluate with the Block List
If it's Matched & Blocked!-> Close the socket immediately -> No need to wait for the body.
Make sure we clean the tunnel -> Remove from the pool if needed. => If it's "Block & Hide"

Note

Beware of this issue on macOS: https://github.com/ProxymanApp/Proxyman/issues/1716#issuecomment-1636619051
When creating a new Block List Rule -> Don't automatically add the URL into the SSL Proxying List -> Otherwise, Proxyman will decrypt the HTTPS data and never release (Hide, but not Block)
