If your expression includes any of the
> characters and you want them to processed as plain text, you need to "escape" the character by preceding it with a backslash. For example, if your expression was
application/epub+zip this would need to be written as
application/epub\+zip otherwise the
+ character would have a special meaning and no matches would be made. Similarly, if the expression was
example.com, this should be written as
. means "any character" which could lead to unexpected matches.
