Hi Experts,<br />
<br />
I have a PAC file that works perfectly with IE9 and Chrome, however doesn't work with Firefox.<br />
<br />
The issue appears to be related to the following code:<br />
<br />
if (isInNet(myIpAddress(), &quot;192.168.1.0&quot;, &quot;255.255.255.0&quot;))<br />
return &quot;PROXY proxy1:8080&quot;;<br />
<br />
If I remove this section, and simply use:<br />
<br />
return &quot;PROXY proxy1:8080&quot;; <br />
<br />
it works fine across all three browsers but I lose the functionality of detecting the client's subnet.<br />
<br />
It could be a bug in Firefox looking at some Google results.<br />
<br />
Can anyone suggest a workaround or alternative method for detecting the subnet? We have three locations with different subnets and different proxies, and roaming users between these sites, so I want the client to use the appropriate proxy at each location.

PAC file not working with Firefox

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

Web Browsers

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
