OTRS 5.0.27, but the same behaviour in other versions.
I have a lot of tickets with .pdf attachements
Every time I want to view these attachments chrome browser try download file insteed simple opening it in internal chrome verwer. On other websites internal chrome pdf viewer works well.
I am not sure if this is related to OTRS, Chrome Browser or base system (apache?), but how to force chrome browser to open attachments from OTRS tickets directly without downloading?
