Cisco 2801 IDS Blocking

Hello Everyone,

I have an interesting issue that I'm hoping someone will be able to assist me with.  Basically I have a subscription to an all online training environment.  They use JavaScript heavily on this site.  When I try to connect into the training environment, portions of the JavaScripts are being blocked and thus preventing me from accessing the site.  I have taken my computer offsite, to my house 8 miles away, and was able to access the site without a problem.  So I know it's not a software issue.  I also have a Barracuda WebFilter 310 in the mix.  I put that in audit mode so that it doesn't block anything and I still get the same result.  Leaving me left with my Cisco 2801 IDS device.

Does anyone have any thoughts on what I can do to ensure that the IDS is not blocking JavaScripts for this site?

The show ver from the 2801 is attached.

Any help you guys can provide would be greatly appreciated!

Final Update.

I was able to find the info I needed on the net to get this configured.  Simple solution.

Define an access-list with all IP addresses to be allowed.
Specify ip inspect name firewall http java-list 10 audit-trail on
Ensure inspect is added to appropriate internet facing interface(s).

Thanks to anyone who viewed and started looking for a solution for me.

I found the issue, it has to do with the IDS blocking java applets.  From what reading I've been doing it looks like if I add an ip inspect rule I should be able to setup an ACL with the appropriate IP's to allow to cross without being blocked.  

Anything I should be aware of regarding how I should go about putting this in?
