The BlueCoat proxy can be configured to redirect users to Kasm and encode the orginal request so that Kasm can navigate the isolated browser to the original request. The following link provides a similar example, except this policy redirects users based on URLs that are not categorized. So the rule needs to be modifed to trigger for all URLs, whith the exception of ‘’ (replace with your Kasm installation domain name). The return code needs to be 302 instead of 307, and the destination URL needs to be modified to ‘$(1)’.
