If you disable automatic proxy caching, Internet Explorer performance may be affected.
Modify the registry
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
You can disable the Automatic Proxy Result Cache by using the following registry key:HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings
Data value: 0 = disable caching; 1 (or key not present) = enable automatic proxy caching (this is the default behavior)If the registry key is not present, you can create the registry key by using the following registry file:Windows Registry Editor Version 5.00

You may have to use this registry key if you connect by using a proxy server that is handling secure and non-secure requests on the same server. One example of this behavior is the SQUID Proxy Server software. Because Internet Explorer typically caches port information, it may not send a secure request over the correct port number when it tries to send secure and non-secure responses to the same server, but on different port numbers.
