The part of a URL that contains information about the content of a dynamically generated page. Web
servers use this information to retrieve the specified content from a database and combine it with a
template to display a page. A Query String can also contain information that is not directly used to
construct a page, but which is intended for use in reporting or other functions. WebTrends’
SmartSource SDC tagging is often used to insert valuable reporting information into the query string. In
many dynamic URLs, the Query String is the part of the URL that follows a question mark.
