I am writing a VBA Excel add-in that uses the MSXML2 object to retrieve data over http. Not strictly a web browser; it just happens to be using the http protocol on port 80.
I know that if the user's Internet Explorer is set up to use a proxy server, then this will automatically pick up their proxy settings.
A user asked me about support for "Proxy.PAC" files, which I know nothing about.
After a little bit of googling, this looks like something that gets used on the browser level.
If a user has a PAC file, can the MSXML2 file use this information to direct its request properly?
Is this automatically supported?
Or is there some extra VBA code I need to add?
Or does the concept of a PAC file only work in a proper browser?
