Hi,

I am not that strong in definitions, so I will just explain how it works.
Postback means that some data are sent from the browser to the server. This
usually happens with the HTTP POST request, hence the name.
The server sends a new piece of HTML to the browser in reply to the postback
(the user would otherwise see a blank page after, say clicking a button)

Like, if you type something in a search engine's "What to find" text box and
click "Search", this is also actually a postback resulting in found links
displayed in your browser.
It's just ASP, Perl or JSP developers don't call it such :-)
 
Hi Alejandro
I would simply say that a page is Postback when it received by the client
( ie from server to client ) for more that once (not the first time) .. so
this means that it has been from client to server and back . hope that
helps
