User Agents

by Vitaly, Monday, April 27th, 2015

“User-Agent” HTTP header allows to identify Internet Explorer version.

Look the following article to learn more about Internet Explorer user-agent strings: Understanding user-agent strings.

Pay attention to the compatibility changes in IE 11:

  • The compatible (“compatible”) and browser (“MSIE”) tokens have been removed.
  • The “like Gecko” token has been added (for consistency with other browsers).
  • The version of the browser is now reported by a new revision (“rv”) token.

Below is the list of some user-agent strings used by Internet Explorer 8-11:
