We are running an website for past 4 years,its use to have an regular cache from Google,But for past September its not cached ,i have created an site map and uploaded in webmaster tool and done some off page optimization too, but yet till now its not cached by Google does any one crossed this issues
if you are referring to not seeing the "cache" link in the serps for your site, it is not necessarily a bad thing. i would double check to make sure you are not using a nocache meta tag and log into google webmaster central to see if there are any messages waiting for you.

Other than a nocache meta tag, what other reasons could Google have for not showing a cache link in the SERPs?
I recently noticed an old page that used to have a cache link, but doesn't now. The page is still doing well in the rankings and getting just as much traffic from Google. It puzzles me that the cache link disappeared, and I'm wondering if anyone can explain it.
It happens all the time, during major back end updates and data movement, for example.
The servers that publish the public cached links are not the same as the servers where the actual ranking analysis is done. Sometimes a public cached page is not available or reachable. And sometimes there still is one, but the date goes backwards from what is clearly indexed, even by several weeks.
When the Supplemental index was easy to explore, it was very clear that a separate record was kept by URL+crawl datestamp. My understanding is that Google keeps all the website data they ever get. They delete user access IP addresses after however many months, but website data lives on and on. You never know what kind of data mining questions might come up in the future, after all.
OK - that's what I hoped you meant. As the rest of this thread points out, that doesn't necessarily mean anything about whether your URLs are indexed or are getting traffic from Google. it's just a weird thing that happens once in a while.
