What is Browser Sniffing?
1.
To detect the name/version of the web browser that has loaded an HTML page. Most often accomplished with Javascript or VBScript.
<script language=Javascript>
if(app.Name == 'Netscape')
{Alert('Using Netscape')}
2.
Checking up on one's web surfing habits.
1. Reading the history of a person's web browser to see where they have been.
2. Pop-up advertising can be activated by active browser sniffing via spyware. The spyware senses that a person has searched for a term or that a term appears on a web page visited by the user and then a pop-up ad appears that is vaguely related to that term.
3. People that surf via unsecured wireless are likely to have their surfing sessions sniffed also.
