How to check? Trial and error.. maybe put a 301 redirect to a simple html page if the condition isn’t met until you have finished testing.

I am using SSIs on each page. When I make .gz file and uplaod it, then the server does not load the SSI. Please suggest me how to include SSI in .gz files.

Use a utility called 7zip (if you are on windows) to gzip these files and give them a gz extension. Then upload them to the same directory where your original js files live. Add the details to your .htaccess file and test using the http://www.whatsmyip.org/ compression tool or Yslow extension in Firefox. Download copies of your jquery.js and jdgallery.js.
