Caching

[manav kher]

Even though I say
setHeader("Caching","no-cache"); in my servlet response

it still does not solve the problem and i have to reload the page to see the modified content
can anyone guess why this is happening. In this case the page reads a variable from the javascript file and the servlet updates the .js file but the variable is still being cached by the client.

There are two possibilities which come to mind here.
The first is that your browser is ignoring your header. Preventing browser caching of pages is strangely complex, and may require setting several headers (pragma, expires etc.) to deal with a reasonable selection of browsers.
The second is that even if this works it will only affect the page in which the header appears, and not other cacheable files such as .js files. In fact, controlling the caching of .js files is effectively impossible. If this is your problem, consider building your page dynamically and including the JavaScript value in the constructed page. Only use an external .js file for static JavaScript.

why don't u add the following header as well and see whether u can manage to get over your problem
setHeader("Cache-Control","no-store");
