Filename extensions are not allowed. (E.g: test.pdf)
Wildcards (*) are allowed in the following scenarios:
A left wildcard must be followed by a period to specify a subdomain.
For example, *.zoho.com is allowed; *zoho.com is not allowed.
A right wildcard must follow a forward slash (/) to specify a path.
For example, zoho.com/* is allowed; zoho.com* or zoho.com/chat* are not allowed.
*.com* is invalid (not a resolvable domain and the right wildcard does not follow a forward slash).
Wildcards are not allowed in IP addresses.
The tilde (~) character is not allowed.
