We have planned, created and launched many of successful websites since our inception, for many different types of businesses around the iran.

Traditionally, web pages have been delivered to the client only when the client requested for it.
For every client request, the browser initiates an HTTP connection to the web server, which then returns the data and the connection is closed.
The drawback of this approach was that the page displayed was updated only when the user explicitly refreshes the page or moves to a new page.
Since transferring entire pages can take a long time, refreshing pages can introduce a long latency.
