Servlet getting cached

[Sajee Joseph]

Hello,

I have an applet that invokes a servlet and send its a parameter 'EmpId'
http://host/MyServlet?EmpId=123.
This servlet gets called several times in my application with different values for EmpId. However i notice that the servlet doesnt get called sometimes. Is there a possibility that My servlet is getting cached ??
If so how can i overcome this??.

Regards,
Sajee

It is quite possible that a proxy server somewhere caches the output of your servlet and returns that instead of calling the servlet when the same servlet with the same parameters is called again.

There's very little that can be done about it. Setting no-cache or expiration request headers and/or meta tags can sometimes help but some proxies simply ignore those.
