What Is a URL Search Hook?In Feburary 2016 14,

A web site's extension is the portion of the URL that is after the last '.' in the address. Examples are .com, .html and .htm. These extensions tell computers what protocol the browser should use to read the web page.
Usage
When the extension is unknown, such as a custom URL, the browser attempts to figure out which protocol to use. A search hook is implemented to determine how the computer should read the web page. Once the search hook has succeeded in reading the page, the new protocol is added to the search hook for future use.
Implementation
The command for a search hook is written into the computer's software as a line of code. The user does not need to perform any special command; the Internet browser will automatically begin to search for a protocol that will read the web page.
