What was the user.agent value for IE11 edge? We are using gwt 2.4.0

Question

I want to make my application compatible with IE11 and edge. I have xyz.gwt.xml file and I have to include compilation for IE 11 and Edge. We are using gwt 2.4.0.

set-property name="user.agent" value="ie6,ie8,gecko1_8"

Answer 1

I have checked it in GWT 2.7. It may be different in GWT 2.4:

IE11 is gecko1_8

Edge is safari

You can check it by yourself by:

• deleting/commenting out the set-property name="user.agent" entry in <module>.gwt.xml file (so, there will be no restrictions on the user.agent)
• starting super dev mode
• opening the host page in IE11 / Edge
• checking in the console, you'll get something like binding: user.agent=safari / binding: user.agent=gecko1_8

Answer 2

GWT 2.4 was released 7 years ago, IE11 two years later (even IE10 hadn't yet been released 7 years ago), and Edge two additional years later.

There's absolutely no guarantee that an app compiled with GWT 2.4 will continue to work in today's browsers (except in browsers that didn't change since then, i.e. IE9 and earlier; but they're now unsupported by their editor(s)). If you need to support IE11 and Edge, you really should update to the latest version of GWT (and, basically, update whenever a new version is released), which is currently 2.8.2.
