When we run our application through a Reverse Proxy (WebSeal) to establish Single Signon, all images of the CuteEditor show as broken images:

 

 

Issue is that the request for these images are being dropped by our Reverse Proxy, because the content type of these images are "Unknown". When we connect to the web-server directly the images are shown, however as seen in the screenshot below they also come up as content type of Unknown.

 

 

We tried to reconfigure our reverse proxy to address this issue, but have not found a way. Is it possible for CuteEditor to assign a proper Mime type of the content loaded by load.ashx?
