Documents shouldnot get stored in Temporary Internet Files folder

GroupDocs.Viewer Product Family
1

Hi,
I am evaluating GroupDocs viewer for Java version 2.1. When I view the document, it is storing a copy in Temporary Internet Files folder of my desktop. But my requirement is, Temporary Internet Files folder should not have a copy of documents viewed. I tried using useCache as well, no luck. Is there any way to do this in GroupDocs viewer?

Server used: Websphere;Browser used: Internet Explorer.

–Regards, Praveenkanna.

Hello, Praveenkanna!

To disable storing cache in the Temporary Internet Files folder there two option have to be disabled:
useCache=false
and 
useHtmlBasedEngine=false

Hi Ihor,
I tried disabling useCache and useHtmlBasedEngine, but still document is getting stored in Temporary Internet Files folder. Is it because I am using evaluation version? – Regards, Praveenkanna.

Praveenkanna, we have investigated this situation a bit deeper and have two solutions for you:
  1. Wait for 2.2.0 release.
  2. Add next code to sample requests:
response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT");
response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");
response.addHeader("Cache-Control", "post-check=0, pre-check=0");
response.setHeader("Pragma", "no-cache");
Each header represents different browsers, IE, Chrome, etc...

This code could be placed in any desired requests/methos.
For example: if you want that only images are not cached into IE temp folder, then this code should be placed here: http://prntscr.com/3rgt1p and so on.

Thanks Ihor. Adding response header in corresponding action methods, worked fine for me. – Regards, Praveenkanna.

Hi Praveen,


Thanks for evaluating GroupDocs.Viewer for Java v2.1.

If you wish I can send you through a 30 day evaluation license to remove all restrictions during your trial, just let me know and I’ll create one for you?

Many thanks,

Derek
