SUMMARY
This article defines the Microsoft support boundaries for customers seeking assistance with Automatic Proxy Configuration (APC) files and Internet Explorer.

The methods that are used to troubleshoot problems with APC files can be addressed by many teams in Microsoft Product Support Services (PSS). These guidelines apply to any group working any issue that specifically involves Automatic Proxy Configuration files.

Issues involving APC files must start with the Internet Explorer team for the customer's support level. The Internet Explorer Support Professional (SP) can start with basic troubleshooting to determine if the problem is in the syntax or network configuration:
 * Is the customer correctly pointing to the specific APC file by using the advanced settings in Internet Explorer?
 * Is the APC file being downloaded and cached on the client computer? The SP may ask the customer to perform a Network Monitor trace or to capture a Wininet log to confirm.
 * Can a simple APC file be processed?



MORE INFORMATION
This is sample code for an APC .pac file: function FindProxyForURL(url, host) {      if (isPlainHostName(host)) return &quot;DIRECT&quot;; else return &quot;PROXY proxy:80&quot;; } Internet Explorer supports all the predefined functions that are available in the Navigator Proxy Auto-Config File Format specification at the link that is listed later in this article. If a customer feels there is a problem in how Internet Explorer is interpreting a function that is being used in an APC file that is supported, PSS will try to resolve the problem by using typical troubleshooting procedures. This will likely involve a request for the customer to produce a short APC file that shows the function problem to reproduce the issue.

Support limitations in regard to all APC related files:
 * PSS will not help in the creation or editing of a customer-created APC file.
 * Microsoft Platforms Support will not provide assistance in developing APC logic for customer environments.
