wat is chache,ipaddress& cookies??

Hi,
It is not chache.It is cache.
cache:
------
when a webclient is connecting with webserver,webclient will request and webserver will respond fro that request.If client is requesting for the same set of values from server repeatedly,unnecessarily some repeated datas would be travelling between client and server.So this might affect the performance.For the repeated datas will be maintained in the cache. The cache is nothing but a buffer(temporary storage area).The repeated datas will be maintained there for some time.There is an option of disabing that option by requesting the server by setting "no-cache".

IPAddress
---------
This is nothing but an address of a system connected in the network.

Cookies:
--------
This is small value which is stored in the client machine for making it to be identified by the webserver.
Since Http is a stateless protocol,It cannot maintain the state of the client.So cookie is used for maintaing the state of the client.
This technique is used in shopping cart applications.

But cookies can be prevented by client.In that case some other session maintaining techniques will be used such as urlrewriting,session API, and hidden fields.

Thanks.Comments are welcome
