Hi Shed,

You wouldn't be able to add them as 'Ensured Types' that MWG could recognize with MediaType.EnsuredTypes (except by submitting a Product Enhancement Request following KB60021).

However, you could add them to a list that is referenced with the property MediaType.FromHeader. This way, as long as the response has a Content-Type HTTP header, you can match against any custom media types.

Let me know if this doesn't work for you or if you have further questions.

Hi we have a Media Type application/unknown ( no entry in Rule Trace ) is this a known behaviour ?

Hello @AOK1971 

application/unknown is not defined in SWG, it may be provided by the original web server, to verify open a cmd or linux terminal and run this command:

curl -I https://<your url>

then check the Content-Type header in the output.

SWG kann "fix" wrong content-type by looking inside of the file and comparing starting bytes of the payload with internal database of known media types, but it is seldom required since SWG can do antimalware scanning disregarding the apparent media type header.

If it only one url or a single web site  then you can ignore it, it doesn't impact security.

Hi,

Hope you are doing well.

Some information on this,  we have : image/vnd.dwg  detection, so  we have dwg file detection.

Looks like below are all same mime types:-

application/acad

application/x-acad

application/autocad_dwg

image/x-dwg

application/dwg

application/x-dwg

application/x-autocad

image/vnd.dwg

drawing/dwg

https://en.wikipedia.org/wiki/.dwg

So looks like we  have the mimetype detection for these.
