UrlReferer

[Daniel Groh]

Hi, I'm trying this line:

if(Request.ServerVariables["HTTP_REFERER"]!="AddUser.aspx")
{
Response.Redirect("AddUser.aspx");
}

But it's not working...I tryed also Request.UrlReferer and didn't work too!

Does someone has examples ?

Try to output the Request.ServerVariables["HTTP_REFERER"] and see if
It returns the value you expected. HTTP_REFERER returns a string
containing the URL of the page that referred the request to the current
page. For example, it may return
http://www.sharingcorner.com/Test.aspx?ID=123. The string comparison
is case sensitive.

UrlReferer is a property that represents HTTP_REFERER -- no need to
hang on to 10 year old CGI style programming practices ;-)

But there's no guarantee that you'll ever receive a Referer, because
this header can be stripped off or manipulated by proxies.

Daniel,

firstly Request.UrlReferrer is not a string to do a
Request.UrlReferrer.ToString() to convert it to string
(check to make sure its not null before)

once you have a string use String.IndexOf() to fin to find if the page
exists in the url referrer string.
