ASP.NET Session State Overview
ASP.NET session state enables you to store and retrieve values for a user as the user navigates ASP.NET pages in a Web application. HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests. ASP.NET session state identifies requests from the same browser during a limited time window as a session, and provides a way to persist variable values for the duration of that session. By default, ASP.NET session state is enabled for all ASP.NET applications.
Alternatives to session state include the following:
Application state, which stores variables that can be accessed by all users of an ASP.NET application.
Profile properties, which persists user values in a data store without expiring them.
ASP.NET caching, which stores values in memory that is available to all ASP.NET applications.
View state, which persists values in a page.
Cookies.
The query string and fields on an HTML form that are available from an HTTP request.

What is OCR ?
OCR (Optical Character Recognition) is the recognition of printed or written text characters by a computer. This involves photoscanning of the text character-by-character, analysis of the scanned-in image, and then translation of the character image into character codes, such as ASCII, commonly used in data processing.
Or, we can say... Optical character recognition (OCR) translates images of text, such as scanned documents, into actual text characters. Also known as text recognition, OCR makes it possible to edit and reuse the text that is normally locked inside scanned images. OCR works using a form of artificial intelligence known as pattern recognition, to identify individual text characters on a page, including punctuation marks, spaces, and ends of lines.
