As per the http status code definitions [w3.org] a 302 indicates a (temporary) redirect.

Perhaps your homepage redirects to another page? (e.g. www.example.com leads to www.example.com/home.htm)

well actuall i have not written any redirection rules in .htaccess file or any where. But when i see the stats for my domain i see thousands of 302 hits to the pages.
i am seeing the AW stats. and i can paste a copy of the stats here.

HTTP Error codes* Hits PercentBandwidth
302Moved temporarily (redirect)534382.4 %27.17 KB
301Moved permanently (redirect)2403.7 %2.29 MB
400Bad Request 3014.6 %0
206Partial Content279 4.3 %1.18 MB

So can you guess why the site getting so many 302 hits.
i see 5343 of 302 hits to the site. is this some thing strange.
Thank you.

It could be a domain redirection, like example.com redirecting to www.example.com. Or, under Apache, www.example.com/home will redirect to www.example.com/home/
