When you’re connected to the internet and using a proxy server while browsing the web, that traffic goes through the proxy server instead of coming directly from your Windows. A proxy server can be used when you’re connected using Wi-Fi or Ethernet. In some cases, your company or organization might require a proxy server. Then we can configure it through UI or registry key. In this article we will tell you some limitations about Windows proxy settings.

Limitation 1: The length limitation for the proxy-override during runtime are 2064 Bytes.

This also includes the appended “;<local>” for the option “Bypass proxy server for local addresses”.

Solutions

In case the list is exceeding 2064 characters and there is no further room for optimization, you need to implement the routing through a PAC-file instead of fixed proxy-settings.

Limitation 2: The character /* is not valid when used at the end of a proxy exception URL.

Actually /* in the end of proxy exception URL is meaningless.

Solutions

To resolve the issue, remove /* from the original URL.

Demo

URLs like http://www.test.com/* or http://www.test.com/ are not considered valid proxy exception URLs.
