Thank you for the infos. I will try it.
As I described in my last post, I tried to accept the download with an exception rule under the threat prevention rule (rule which blocks all exe downloads). Now it seems, that the rule works, but only if I write the URL as a Regex expression and not as a wildcard.
So the regex works: .*\.heise\.de.* but not the wildcard *.heise.de or *.heise.de*. Is the syntax of the wildcard false? Is this also a correct way if i define a Threat prevention exception?
Thanks.
