What are HTTP full headers

The use of full headers is preferred for several reasons which are as follows:

  • The first line of a server header includes a response code indicating that the success or failure of the operation
  • One of the server header fields will be Content-type:, which specifies that a MIME type to describe how the document should be interpreted.
  • If the document has moved, the server can specify its new location with a Location: field and allowing the client to transparently retry the request using the new URL.
  • WWW-Authenticate: and the Authorization: fields allow access controls to be placed on Web documents.
  • The Referer: field allows the client to tell the server the URL of the document that triggered this request and permitting savvy servers to trace clients through a series of requests.

What is HTTP

HTTP Stands for Hypertext Transfer Protocol.

It is basically used to communicate web pages to web browsers,(HTTP) is used by web servers.When your browser connects to a web server, requests a web page from the server, and downloads the page,HTTP is used. It is a common standard that enables any browser to connect to any server, anywhere in the world.

HTTP was originally designed by Tim Berners-Lee to support the special demands of web communications and with an emphasis on efficiency, and a target page load time of under a tenth of a second. Modern Internet networks can support this type of response provided the page isn’t too large and the server is too far away.

To download different parts of a web page, downloading the text, graphics, and other objects on the page in different orders,your browser can open more than one HTTP connection at once. That is why you may see the status messages in the bottom of your browser window switch between a message like “downloading 38% of 47K” to “downloading 62% of 15K” on the same page — there are different HTTP connections.

To specify the download priorities,some browsers enable you so that, for example, graphics are not loaded, text is loaded before graphics, everything is loaded at once, etc and check your individual browser preferences

DOT NET – Maintaining user information for Security & other requirements

– Create login.aspx in the root directory and design the page according to requirement. Code for this should be written after completing preperation of Entities, DL, BL and others…..

– Goto DB that the project is configured and create tables for storing user information. In general userinformation will have multiple tables, many columns but in our example
we will create users table with username(pk),password,role.

– Add some sample data in the created table and optionally write procedures for accessing the created tables.[In real time highly recommended is access tables with procedures]

– Once db is prepared we have to prepare front-end layers and as usual we will use EDM(O-R) for preparing our objects. prepare edm objects.

– once EDM objects are prepared we have create BL for users where we have to provide all functionality.

– Now we can write code for login button of login page. In this button we have to pass userdetails to bl and on successfull evaluation i.e when it returns true we must create forms identity.

class prjuser
string _uname,_password;



c1 obj=new c1();

class c2 : c1

DOT NET – What is a cookie

Recently I got a message from one of the reader of my site that what exactly is a cookie. So I decided to wire a post dedicated to it .

  1. A cookie is name=value pair like variable which is stored as a file(persistant cookie) and which travels automatically between every request and response.
  2. Cookies are based on domains(website). As long as user is working with current web site cookie will be available.
  3. Cookies are maintained by browser but not by server which means cookies based websites are dependent on client.
  4. Cookies can be created as
    (i) In-memory cookie
    (ii) Persistant Cookie

An In-memory cookie means as long as user is working with app it will be available – also called as Session Cookie.

Persistant cookie means it will be stored in client physical location and available online as well as offline.
