## Symptoms

- Issues with traffic and with web pages when Security Gateway is configured in Proxy Non-Transparent mode:

* Web traffic is slow
* Download breaks
* Downloaded large files are corrupted (MD5 does not match to that on the hosting web site)
* Some clickable buttons inside the loaded web page are not working / disabled

## Cause

When Client sends several sessions to same Destination host on the same connection, Security Gateway in Proxy Non-Transparent mode does not resume the existing connection (it does not reuse already created server connection to the same host) - it opens new connection for each session instead.
