Request.Servervariables("HTTP_REFERER") Versus BACK Button On Browser
When my webserver does not process a user's change because of an invalid password, I inform the user and I want to present them a button for a retry:
<TR id=continuebuttonrow>
<td width="05%"> </td>
<TD width="90%" align=center valign=middle colspan=2>
<BUTTON TYPE=BUTTON
ONCLICK="location.href='<% =Request.ServerVariables("HTTP_REFERER") %>';"
class=btnParms name=btnContinue ID="Button3">Try Again (Back)</BUTTON>
</td>
Yet if this button is clicked, they go back to the server and the page is refreshed with original values.
If I click the browser's BACK button (rather than my button above), I go back to the page (from cache I guess) I want (because it contains the user changes). Here I can correct the password without having to rekey the changes.
So, what is the Request.Servervariable needed for the equivalent of the BACK button?

I have a "Email this page to a friend" form that submits to itself and contains the hidden input value="<%= Request.ServerVariables("HTTP_REFERER") %>".
The value="<%= Request.ServerVariables("HTTP_REFERER") %>" is to obtain the URL of the page that the person wishes to send.
The problem is, if someone creates an error in any of the input fields, the page submits to itself again and displays the errors. When this happens, the original HTTP_REFERER url address is lost and now replaced with the url of the "Email this page to a friend" page.
Is there a way to retain the original HTTP_REFERER value even though the user refreshes the page?

Found this funny error on a clients computer the "request.ServerVariables("HTTP_REFERER")" does not show any information on the previous address of the last webpage visited. The computer does how every show the details of "request.ServerVariables("ALL_HTTP")".
I can't seem to be able to duplicate the problem on my computer. Does any one have any ideas why this might be happening?

On a current website, when I submit a search from a form, the page with results are shown. If I then click page 2 of the results I get page 2 no problems. The PROBLEM then is a user clicking the browser back button. When this is pressed IE shows this error which makes sense but sites like play.com dont have this problem. Quote:
Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you. To resubmit your information and view this Web page, click the Refresh button.

I am trying to write a small banner system and I am trying to get the page from where the banner is displayed. I have tried this piece of code:-
page = Request.ServerVariables("HTTP_REFERER")
however with IE6, it does not work and gives me a blank variable.
Is there a way round this?

I know you can not disable the browser back button but I have a script that grades online tests and when they click the, Grade test button, it works great. But if you click the back button, you can go back to the page and change the answers to the questions. So like this, if one failed the test they could simply click the back browser button and redo the test.
What I need is away to not disable the back button but maybe if they click the back button to take them back to the registration page to register for the test again. I have tried a few lines of code with "no-cache" and it would show expired but I prefer a redirection to the registration page if posible. how this could be done when clicking on the browser back button?

I want to understand the difference between submit button and regular button: <input type="submit"> and <input type="button">. My understanding is that submit button will send the entire HTML form to the web server, but regular button won't.
I have a problem that needs to pass HTML elements data back and forth in several ASP pages. I am using regular button to do that. But what's the approaches?

I have a form that submits values to an asp page. If their is an error on the asp page that is called and you go back to the first page with the form. The values are not in the form.
How can I set the value back into form without the user having to retype them in? If I use hidden fields on the first asp page and I go back to that page wouldn't the values for the hidden fields be empty as well?

I am trying to use Request.ServerVariables("SCIPT_NAME") - this is
ok normally, but when I try to use the script behind SSL - it does not
pick up the full path to where I am - eg:
https://sslrel.com/sslcert.mysite.co.uk/Default.asp
Request.ServerVariables("SCIPT_NAME") in this file, would show:
https://sslrel.com/Default.asp
Which makes all my redirects etc - not work!
Is this a known feature of SSL, or has it just been setup incorrectly?

Our intranet was running on a Windows NT4 server using IIS4. We have just upgraded to Windows 2000 & IIS 5 but we are now having a few problems.
A lot of our code uses Request.ServerVariables("auth_user") to get the users logon name. This used to work fine but now it doesn't work at all. We don't get an error, just a blank value.
I have searched around for help but it seems that there is no reason why it shouldn't work, which makes me think that maybe it's not the code that's the problem.

I have had issues with Request.ServerVariables("HTTP_REFERER") because it seems that in many cases it returns an empty string or NULL value. I use it when it works correctly to enable my scripts to be somewhat universal, not requiring hard coded values or "email an associate" scripts etc.
I just noticed that a script I'm working on does work in FireFox but not in IE. I've run the script in XPPro as well as Win2K Server to rule out it being a local setup problem. It seems that if I use Javascript to open an new window FireFox recognizes the referer but IE does not.
I realize this is probably a difference in the way IE handles the Javascript function of opening the window but as it is a Request.ServerVariable that is not being passed maybe someone else in ASP-land has run into it and knows a fix.

i want to know the usage of Request.ServerVariables.I'm not sure this is really a ASP question,so redirects to a more appropriate newsgroup are welcome.
I have a variable that is being passed to me through HTTP headers "Test."I am able to see this variable and its value when I use Request.ServerVariables("ALL_HTTP").
when I iterate through Request.ServerVariables using a "For Each key in Request.ServerVariables" the key of "Test" comes up.However, when I use Request.ServerVariables("Test"), the value returned to me is always empty.

I have an ASP page which collects the "logon_user" and assigns different permissions based on their "names". It is working properly under Windows 2000/XP, but Windows 9? is NOT recognizing. Could anyone tell me what I have missed? Updating new versions or changing my code?

I have written an application that catches the logon user's name in order to assign different levels of permissions, but the users logon under different OS (Windows versions).
the "logon_user" is recognized under Windows 2000/XP but not Windows9x. The server is under Windows 2000 which connects all kinds of workstations with different OS. Do I need to update the pathes of Windows9x or I need to use different Server variable to catch up the logon user's name?

We have the Request.ServerVariables("SERVER_NAME") used in a classic ASP page using IIS 6.
It used to return our website name: www.xxx.name.this when using IIS 5, now it is returning the IP address when we type the full www. url.

I am running Server 2003 and ASP. I used the following code to loop through the variable collection:
for each obj in Request.ServerVariables
response.write "Object Name: " & obj & "<BR>" & "Object Value: " & Request.ServerVariables(obj) & "<BR><BR>"
next
I got the list of all the possible objects as expected, but the majority of the values were blank. I am designing my site so that there is a seemless login capability. When you log into the domain, your credentials are verified through NT. I was going to use one of the available server variables to grab the user name for login purposes, but found all the values blank.
Is there a known bug/issue? Is there a configuration setting in the IIS MMC that I have overlooked that will allow those values to be tracked by the server?

I am coding a login system with login form etc. and when users are denied access to a secure page within the secure area, I want to obviously send them to the login page to check who they are and check they are allowed to view the secure content of the site.
The problem I am having is that currently, if a user is denied access to a secure page, they are sent to the login page. Once they are granted access, they should be sent back to the page they were originally trying to view and not to the main menu.
(The secure area has lots of pages and users would not be happy if they had to trawl through hundreds of pages to try and find what they wanted.
I know I need to use the ServerVariables collection to retrieve the ("URL"), but I dont want to just use this as a querystring parameter when I send a user to the login page.
This would be insecure because someone out there would find my little login script and start using it on their own site by sending users to my login script to login, and then using the querystring parameter to redirect the user back to their own site.
All I want to do is select the part of the URL after the http://www.somedomainname.co.uk/manager/ part. I cannot use a Left select or right select option because my login script will be put onto lots of different websites, and I would have to change the Left select on each different site.

A few days ago all my Request.ServerVariables began coming up empty. I was using Request.ServerVariables("AUTH_USER") for basic authentication but now its useless. Our server administrator tells me he installed some "patches" last week but doesn't think he caused the problem. All I can say is that before the patch they worked fine. Anyone have any ideas on where to look for a solution?
