Autorization using Get and value
<p>I want to authenticate a request - passing it the - and then it stranivaya on the server if the same - that avtorihovalsya - if not, then there is no</p>

<p>What can be done iskusttveno - without using controls (using the classes as well):
  Translate user from nezaregestirovannogo in zaregestirovannogo:</p>

<p>For example:</p>

<p>I make a request <a href="http://Login.aspx?Hash=jiojor" rel="nofollow">http://Login.aspx?Hash=jiojor</a></p>

<p>Check in Page_Load if the database user with the Hash = jiojor</p>

<p>If yes, then:</p>

<p>Register.User (nameUser) = true
  And the user is logged in nameUser</p>
