I have a Sharepoint 2013 environment that has configured a BLOB cache, so that it caches all PDF files. This is configured on the 2 WFE. After the configuration, I have experienced that, if you overwrite a PDF file with a new version and then open the PDF in the browser, it will still open the old version.
If I download the file and open it in adobe, it will show the new version.
When I go to the location of the BLOB cache, I cannot find the PDF file, even though I have opened the PDF file from SharePoint. All the other files from the same Document Library are shown, when they have been opened.
For now I have tried to clear both browser-, BLOB- and SharePoint cache. Nothing worked.
Has anyone else experienced this issue?
