It sounds like the firewall doesn't like the html file that is  
composed entirely of javascript. If you have access to the IT  
departments that run those firewalls, perhaps you could request that  
they disregard that rule for your particular sites.

If that isn't possible you could maybe try using the XS linker to  
generate cache.js files (usually used for cross site loading) and  
perhaps the firewall would allow those to pass unmolested.
