Two methods for accessing the user agent string include:
A broader UA definition includes Web crawlers, Web bots and other technologies. The browser issues certain UA strings that show the specific technology used to access a site, page or other content. For example, a UA string from a Firefox browser would include the word Mozilla, as well as version data and other details.
