hi all,
we have a internal URL, that works fine when we bypass ASA and doesn't open via ASA, I have tried the steps as adviced in the following link but issue still is same.

Please let me know if there is a option to disable javafilter in ASA. Thanks in Advance!
cheers!

Hi Varun,
Thanks for your prompt reponse. Sorry, couldn't uptdate you the config, this is a client's box.
Could you suggest me any steps to test if the ASA is blocking the javascript and if there is a way to disbale.
cheers!

Well not really sure if its a java issue only because you first need to verify whether the config is good for it or not. Are you doing u-turning on the firewall, could you just post the config relevant to the server?

no u-turning confugured, unfortunatly dont have much of the config, it just has a access-list allowed for http port to the server and route, default inspection enabled are.
