MailHASH Hash an URL
You are about to creat a unique HASH for an URL. You can do this on domain base, for example www.site.com and www.site.com/files.php will use the same HASH.
The HASH this creates is needed in the JS call to the MailHASH functions. In the code below you see {hashkey} where you should place this hash.
Note:
If you want www.site.com and site.com both to work, you will need to create 2 hashes, one for each domainname.
