doesn't affect how it works in the browser:
Cfif isdefined(cgi.HTTP_REFERER) and (cgi.HTTP_REFERER CONTAINS
#articleID# OR cgi.HTTP_REFERER
such variables if they don't exist. So, for example, this code would
work:
cfif CGI.FOO_BAR is not baz
even though there's no variable called CGI.FOO_BAR.
Second, and more important, you can't rely on CGI.HTTP_REFERER for any
serious security anyway, since it's sent by the browser, and can easily
=page_to_clear
input type=submit name=submit value=Submit
/form
/cfif
...the final page checks for the cgi.http_referer, and if it exists, it
performs a specific action:
cfif CGI.http_referer CONTAINS clearpage.cfm
...do something...
/cfif
However, the http_referer variable is always returned
Yes there!
This may sound overly naive but, on the index page of one of our web
applications,
I have done a check for the #cgi.http_referer# environment variable.
Then I have done a search through MNS (per say), where it links directly to
the (URL AND) template, the variable is defined
Hi All,
As I understand that cgi.http_referer created by the browser only when
the user follows a link or submit a form to the current page. So
sometimes it could be blank.
With this in mind we put this piece of code in our action page:
cfif attributes.method contains Action
cfif

So the question is:
Is there any other situation when the cgi.http_referer would not be get
set
this to happen?
Thank you again.

Short answer: Yes.
I've been running and logging referer tests for about 6 months now. I
get

I guess we cannot do anything to prevent this to happen?
Thank you again.
