Internet Explorer - How to force compatibility mode for certain sites?

Question

I would like to force IE10 to render certain sites from my intranet in IE9 mode.

I have tried using the local compatibility list to no avail (%LocalAppData%\Microsoft\Internet Explorer\IECompatData\iecompatdata.xml). I have tried adding the following entry into that file:

<domain docMode="EmulateIE9">projects.mycompany.com</domain>

Is anybody aware if this is possible? Or maybe there's an add-on for inserting a doctype on the fly?

I could also use fiddler for that, but I would like to know if there's no simpler solution.

Update: to clarify, I need a solution that works client-side. I have no access to the servers. I might want, for instance, to modify the headers (insert a DOCTYPE) in a certain page from http://abc.com, to which I have no access. I could do that with fiddler or something like GreaseMonkey (Trixie for IE), but I am first looking for an easier solution before dirtying my hands.

Answer 1

You can specify sites for the Compatibility list (including subdomains) by doing the following:

1) Open up Local Group Policy Editor (Windows Key+R & type gpedit.msc)

2) Go to:

Computer Configuration/Administrative Template/Windows Components/Internet Explorer/Compatibility View

3) Edit the Use Policy List of Quirks Mode sites, enable it and add sites to the list of sites

4) Reboot and try those sites
