if it would make diff. but the article in the link says something has changed on install of plugin under 8

Hi All,

Maybe someone can help me out here. We have a document management system written in Witango, and as part of the system we restrict access to files based on the users profile. When a user requests a file, we check their credentials and then send the file back to them using the following (where fileContents contains the contents of the file):

<@PURGERESULTS><@ASSIGN request$httpHeader "HTTP/1.1 <@HTTPSTATUSCODE> <@HTTPREASONPHRASE> <@crlf>Server: Witango <@version><@crlf>Content-Type: application/octet-stream; name=<@VAR LOCAL$fileNameENCODING=NONE><@CRLF>Content-Disposition: inline; filename=<@VAR LOCAL$fileName ENCODING=NONE><@CRLF><@IFEXPR='len(<@USERREFERENCECOOKIE>)' TRUE='<@USERREFERENCECOOKIE>'><@crlf>"><@VAR local $fileContentsencoding=none>

This application was untouched for some years, and it always served the files correctly including PDF files. The user got the Open, Save and Cancel dialog for known file types. However, after we installed Adobe Reader 8.0+, we no longer get the option to Open the PDF files directly, but can only Save them to the file system. I have included the HTTP response header below. Should Content-Type be set differently to give the Open option? If I specifically set it to “application/pdf”, I get the open file option, but I cannot do this as we server all different file types. Maybe someone is doing something similar and may have run into the same problem.

-----------------------------------HTTP Header------------------------------------------
HTTP/1.1 200 OK
Server: Microsoft-IIS/5.1
Date: Thu, 13 Dec 2007 11:39:32 GMT
X-Powered-By: ASP.NET
Connection: close
Server: Witango 5.5.003 Liquorice (Win32)
Content-Type: application/octet-stream; name=Certificate.pdf
Content-Disposition: inline; filename=Certificate.pdf

PDF contents start here……

Any help greatly appreciated.

Thanks
Mike.
