I'm trying to understand where I can configure a request timeout for all requests arriving to a servlet of mine (or all of my servlets)? Is that, as I think, a container property? Also, how does this affect different browsers? Do they all comply to the parameter the container dictates? Or maybe the request timeout time isn't even something I can control and each browser decides on this on its own? (Just to be clear I'm not talking about session timeout)

Timeouts on http. request() takes a timeout option. Its documentation says: timeout <number> : A number specifying the socket timeout in milliseconds. This will set the timeout before the socket is connected.
For HTTP servlets, parameters are contained in the query string or posted form data. If the parameter data was sent in the request body, then i occurs with an HTTP POST request. Data from the query string and the post body are aggregated into the request parameter set.
The timeout from a client (i.e. how long it waits for a response to an HTTP request) is determined at the client. For IE, see this, and for Firefox see this.
You can't control this timeout from the server.

Even though you can't control client timeout, you can make server very impatient :) For example, on Tomcat, you can do this in your connector,
<Connector port="8080"
...
connectionTimeout ="5000"
disableUploadTimeout="false" />
This makes server only wait 5 seconds and close the connection. Browser will get a connection closed error. You can treat it the same as timeout in client.
Of course, this only works if the timeout is caused by the server, not connectivity issues between browser and server.
