## Symptoms  
- After upgrading a Security Gateway, when traffic passes through the Security Gateway acting as an explicit HTTP/HTTPS Proxy (port 8080), websites may load very slowly or only partially.

## Cause  
A code limitation causes incorrect HTTP/HTTP2 header processing in the proxy, leading to slow, partial, or frozen website loading.
