Request Filtering file extensions causing issues in V9

We found that the usual request filtering we use by extension that was working in V8 is now causing lot's of 404's and the CMS fails in some areas in V9. I beleive it might be something to do with the WebSockets use in V9. Examples below:

http://blah.localhost/EPiServer/shell/Stores/profile/editlanguage_blah.localhost?dojo.preventCache=1475735871750
http://blah.localhost/EPiServer/shell/Stores/profile/epi.selected-comparemode-id?dojo.preventCache=1475735871818
http://blah.localhost/EPiServer/shell/Stores/metadata/EPiServer.Core.ContentData?modelAccessor=%7B%22contentLink%22%3A%22650_3098%22%7D&dojo.preventCache=1475791458610

We take away the request filtering and the CMS works properly again. Heres what we use.
