Re: [mod-security-users] checking single parameter value

[Alex V. <ale...@ss...>]

AFAIK, md5 are only hexa values... So yours (with other chars) aren't
md5... but it's not really your problem there...

I think this should work :
SecFilterSelective REQUEST_URI "^/mls_verifyemail.php"     chain
SecFilterSelective ARGS_hash "^[0-9a-zA-Z]*"        allow
