I am writing a document to help users of our product access our web application if they are going through firewall/proxy and they don't have any IT resources to help them resolve why they have accessibility issues, which does occasionally occur.
So far I have the following points:
Exclude domain from proxy direct/transparent
Exclude domain from HTTPS inspection
Exclude domain from DNS caching
Exclude domain any authentication whitelists
Disable Addons in Browser
Try using Firefox/Chrome if you are using IE
Any assistance is welcome.
