caching - Google chrome same url cache -

-

i'm testing servlet using google chrome. when tried load same url twice, say,

localhost/myserver/servlet

chrome sent out 1 request server. however, if modified second url be:

localhost/myserver/servlet?id=2

it sent 2 different requests. i've enabled incognito mode, seems chrome shares cache , urls between incognito tabs.

caching control part of http specification, read it. using http headers cache-control: no-cache or expires: ... should you.
