It currently isn't possible to create a file-blocking exception based off of the files name. I'm actually not sure how you would go about working around this limitation since you are trying to allow a file based off of it's filename; it's relatively easy to do the opposite and block specific filenames, but you can't reverse that to allow the file.
Hi @dmodi ,
What @MMadrala have suggested is really great idea.
I what thinking for another way - you can create custom application which look at HTTP response headers for Content Disposition and look for specific filename http-rsp-headers Context (paloaltonetworks.com)
I haven't tested it, but I am imagining
- you create a rule using the custom app and apply file blocking profile allowing txt files
- below that rule you have your default rules with file blocking profile blocking txt files.
