EX SSL-VPN: MIME type changes when uploading doc and xls files to Live link server via EX SSL-VPN device
Resolution
Question:
Representation of file type changes when we upload DOC and XLS on Livelink server, with and without Aventail agents the behavior is same, we are able to see the file extension properly on the server but users are unable to edit the files, if we modify the files manually on the server then users could edit the files properly, but they cannot go and edit all files when they upload to Livelink server via workplace since they will be uploading 100’s of files every day.
This server looks like SharePoint but not the same, when we upload the files without aventail Mime type will show in this format “Set content type toapplication/x-www-form-urlencoded”.
When files are uploaded through our SSL VPN to Document management system (Livelink), Aventail is setting the content-type incorrectly. When the application is used externally through the SSL-VPN appliances - "Set content type to application/x-www-form-urlencoded". It's the same MS Word document being uploaded in both logs.
I have attached the screenshots for your reference, this screen captures contain what happens when we upload DOC and EXCEL files on Livelink server via aventail.
Screeenshot #1 shows it will upload files with the proper extensions, but representation doesn't show properly and users can't edit the files
Screenshot #2 shows, when we upload .XLS and >DOC it will add MIME type as mentioned in the above description
Screenshot #3 shows it supposed to set the Mime type VND/application, if we set the mime type manually it works fine, since users uploaded large number of files we can edit each file on the server.
Resolution/Workaround:
Test patch provided to customer and issue is fixed, per engineering we are not going to release any hotfixes, the fix will be pushed to version-9.0.5, 10.0.3 and 10.5 and all the latest releases.
