Actually HTTP request is used for call the action in dynamic website to navigate so how does this action takes place?

HTTP is The request which your computer sends to the web server contains all sorts of (potentially) interesting information.

HTTP is the foundation of data communication for the World Wide Web.

The HyperText Transfer Protocol (HTTP) is a request/response protocol that is used by clients (typically Web browsers) to exchange information with servers (typically Web servers). An HTTP request is simply a MIME-like message that the client submits to the server to request data. Here's a very simple example of an HTTP request message:

GET / HTTP/1.1
Host: google.com
User-Agent: Mozilla/5.0

Upon receipt of this request message, the server responds with an HTTP response message. This response might be a redirect (3xx response code), a successful response (2xx response code), or an error.

For detailed information about HTTP requests and responses, consult RFC 2616.

In layman's term, it's just simply typing the url of the site on address bar of the browser and when he press enter or click go, the http request is in progress.

Meaning of HTTP - "Hyper-Text Transfer Protocol" is the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.

Yep, agreed. HTTP is a request/response protocol, from your IP address routed to the requested server where file is.

The information, in the form of a text record, that a users browser sends to a Web server containing the details of what the browser wants and will accept back from the server. The request header also contains the type, version and capabilities of the browser that is making the request so that server returns compatible data.
Upon receipt of the request header, the server will return an HTTP response header to the client that is attached to the file(s) being sent.

Whenever your web browser fetches a file (a page, a picture, etc) from a web server, it does so using HTTP - that's "Hypertext Transfer Protocol". HTTP is a request/response protocol, which means your computer sends a request for some file (e.g. "Get me the file 'home.html'"), and the web server sends back a response ("Here's the file", followed by the file itself).

HTTP Request overload is when a sites web page has too many images, Stylesheets, Javascripts, and other embedded elements in it, and because of the number of external files the page is slow to load.

HTTP stands for Hyper-Text Transfer Protocol it is a request/response protocol..and HTTP request means your computer sends a request for some file (e.g. "Get me the file 'home.html'"), and the web server sends back a response ("Here's the file", followed by the file itself).

It is basically a kind of encryption on the world wide web.

Otherwise everything you entered would be visible for everyone else to see, and all of your internet history would have been revealed to the world! :p
