HOW TO CHECK OFFLINE WORKING: open the URL when internet is connected.close the browser after loading all contents. now disable internet and load that URL again it should show the the data from cache.

The above is working fine in Firefox but not in Safari.

May anyone can give me the solution...

I will be thankful

Make sure that the manifest file is served as type text/cache-manifest. There are several other guidelines worth checking in Apple's developer documentation for iPhone and Mobile Safari.
