I am using MVC 3. I am opening new tab on button click and in new tab i open one view in which have on iFrame and iFrame load pdf file.
This is work fine but When i open again then it display old file instead of new file. File name is same but file content is changed.
Updated
If pdf file name generate random then its work fine but i don't want to do this.
