What is difference between PAC file and Proxy.

Jump to solution

Hi everyone,

In our environment we have deployed  Computers with both PAC file location and Proxy.

We are using MWG  7.4

Need to understand difference between these two deployments in MWG?

Also need to know when we should config  PAC file settings in IE on user PC and when we should config  proxy server settings on IE?

Regards

Mike

Setting proxy configuration in browsers is not a specific task related to MWG but it's a much wider topic, it's all about finding the right proxy server. The main difference between PAC file and setting for proxy server:

- proxyserver: one proxy server address and port and maybe some exceptions for direct access to webservers: valid in simple environments

- PAC file: file containing a javascript function named FindProxyForURL(url, host), which is called automatically by the browser for every webserver name. Using this you can have a very flexible or even dynamic solution. There are many resources on how to code your PAC file you may start with Proxy auto-config - Wikipedia, the free encyclopedia
