Caching files on reverse proxy

[vara prasad <vprasad.pendyala@xxxxxxxxx>]

Hi  All,

I have set up a reverse proxy www.example.com for an internal tomcat server http://internal:8080

Few files are hosted on  http://internal:8080.  

My requirement is when user downloads a file from http://internal:8080 using the proxy, the proxy should cache the file with its original extension. A .pdf file downloaded from  http://internal:8080 should be available in the reverse proxy's cache as a .pdf file.  Can any one help to get to it? 

Thanks in advance.
