Be able to dynamically modify the static html pages to force IE Browser modes

[deanapeterson]

It would be nice to be able to open IE in it's different browser modes.

I was hoping to find a find a command line option to do that, but there is not. In lieu of that is it possible to dynamically set the following header in the static html pages?

<meta http-equiv="X-UA-Compatible" content="IE=[VERSION]">

Is this possible? or desired?

Nice idea!

Anybody willing to give it a try ?

Or we could set HTTP header.

How about this?
Laucher can pass URL params (it currently does id). It can pass "ie" param (such as ie=edge).
The web server, when serving index.html, will check that and set correct headers.

Then, you can configure multiple custom launchers - starting for instance multiple instances of IE11, each in different compatibility mode.

Http header would be much preferable to a meta tag. Switching via query string is a great idea. Presumably the default value would be edge?

@WickyNilliams yep, do would you like to give it a shot?

I'm not a node dev but I'm sure I could give it a go. Could you point at me files I should focus on? How generic do you think it should be? Should I be able to specify any HTTP headers to be sent?

[vojtajina]

I think this consist of two things:

• the web server (karma middleware), when serving client.html has to read the ie url param and set appropriate header
• the karma-ie-launcher has to read the param from the config (see how karma-chrome-launcher allows to pass flags etc.) and pas it when starting IE
