Hi Experts

I have a problem with the .DOCX Mime Content type we use. I have correctly set the MIME type on my IIS server (V6) as

".docx","application/vnd.openxmlformats-officedocument.wordprocessingml.document

When I retrieve a test document form the site using a direct link, eg

http://mydnnsite.com/portals/0/test.docx

the HTTP header is:

HTTP/1.1·200·OK(CR)(LF)
Content-Length:·9977(CR)(LF)
Content-Type:·application/vnd.openxmlformats-officedocument.wordprocessingml.document(CR)(LF)
Last-Modified:·Fri,·12·Mar·2010·02:37:35·GMT(CR)(LF)
Accept-Ranges:·bytes(CR)(LF)
ETag:·"a5715ef98cc1ca1:ed2"(CR)(LF)
Server:·Microsoft-IIS/6.0(CR)(LF)
X-Powered-By:·ASP.NET(CR)(LF)
Date:·Fri,·12·Mar·2010·02:51:30·GMT(CR)(LF)
Connection:·close(CR)(LF)

 When I then use the link module and reference this as a File Link the URL

http://mydnnsite.com/LinkClick.aspx?fileticket=gln6elZuXys%3d&tabid=97&mid=2045

shows the HTTP header as

HTTP/1.1·200·OK(CR)(LF)
Connection:·close(CR)(LF)
Date:·Fri,·12·Mar·2010·03:22:56·GMT(CR)(LF)
Server:·Microsoft-IIS/6.0(CR)(LF)
X-Powered-By:·ASP.NET(CR)(LF)
X-AspNet-Version:·2.0.50727(CR)(LF)
content-disposition:·inline;·filename="Test.docx"(CR)(LF)
Content-Length:·9977(CR)(LF)
Cache-Control:·private(CR)(LF)
Content-Type:·application/octet-stream(CR)(LF)
(CR)(LF)

Note the different Content-Types.

The problem truly manifests in IE7: In the first case IE opens the file in word, but in the second case it regards it as a .ZIP file (which it is) and wants to save it as a .zip file, rather than opening in Word. Firefox 3.6 does not show this behaviour.

My client is not happy and wants this resolved. I am thinking that DNN mangles the content type that IIS would normally show when it writes the headers.

I am crossposting this to the Links and Filemanager module forums. Any feed back much appreciated!

Regards

Felix Burkhard

While working on a Silverlight image editing and uploadcontrol the other night I noticed similar behavior with png files.

When adding a file to the Files table or when streaming content to the browser, DotNetNuke determines the content type based on the filename extension using a call to the shared method DotNetNuke.Common.Utilities.FileSystemUtils.GetContentType. Unfortunately, the method has not been updated to handle any of the newer filename extensions and content types. All others default to "application/octet-stream".

I will add the issue to the Gemini support system.

 We just noticed this today (we don't usually upload .docx files). Any update on this issue?

The issue number in Gemini is DNN-11895.

While it has been verified it is not yet on the roadmap for the next release DNN 5.4.2.
