Amos, thank you for the details.
Need pointers for caching the dynamic contents. My app has static n dynamic
cache n static am able to cache it . For dynamic the URL is getting
appended with query string.  Is there a way to cache dynamic contests n
what would be configuration changes to cache dynamic ones.
Thanks a lot.
