Should I Use Count To See If Button Was Pressed?
So far I've been using instructions like 'if request.form("var.x") <>
"" then ...' but then I found that if images are disabled (or not
found) and I click on the alt text, then Firefox (or was it IE?) sends
a 'var.x=' in the response so my instruction doesn't detect that the
'button' was pressed. Is it safe to change my checks to 'if
request.form("var.x").count 0 then ...' instead? does it work for
all browser responses and HTML standards, etc?

View Replies View RelatedASP - Form Redirect To Same Page - BACK Button Does Not Work ???
I have created 2 asp pages called testa.asp and testb.asp
testa.asp has a link to go to next page testb.asp
testb.asp has a form that ask you for a reference number and post it
to the same page testb.asp
If the reference number is not blank, it will just write out what the
reference number is.
Now my problem....
If you go to testa.asp and click on the link to go to testb.asp you
will see the form. At this point, if you click the back button, it
till take you back to testa.asp ALL FINE SO FAR.
If you go to testb.asp again and see the form, enter a number say 33
and click on search. This will now show you the number you have just
entered. NOW - click on the BACK BUTTON, it will just show you exactly
the same page ! WHY does it not go back to the FORM in order to refill
in a different number. Code:

Security :: Prevent Users From Submitting HTML Pages From Their Local Machine
I am trying to prevent users from submitting HTML pages from their local machine to our website and I was wondering what the best way of doing this was.
I was thinking about using the HTTP_REFERER server variable (to check where the user has submitted a page from) as a blanket fix however when you use the javascript document.location on a page the HTTP_REFERER is always blank, which makes that a flawed fix.
I have seen other sites protect against this, so I know it can be done. Whats the best way.

View Replies View RelatedMultiple Users Accessing Database
When more than one user tries to access my system, one user gets his page processed, and the other users recieve an error message stating:
Microsoft JET Database Engine error '80004005'
Could not use ''; file already in use.
/processweb/html/cpr/admin/sel_sc.asp, line 25
I am using ASP 2, MS Access 97 and IIS 4. Any ideas why only one user is allowed to access the database simultaneously? The database file itself is closed.
I have a hunch it may be because the IUSR_[machine name] user account on the web server does not have access to the *.ldb database locking information file... Does this sound like a plausible reason?
Refresh Button Resubmitting Data - How To Prevent This?
My application is written in .NET (C#) with the inline Edit mode from
DataGrid. When a SAVE button is pressed it will perform a action on the
database either to add, edit or delete data that a user has entered.
When the refresh button is pressed at the top of the page the same
exact data is re-submitted again resulting duplicate transaction in the
database. Is there anyway of stopping this happening? From client-side
script, how can we detect that the "Refresh" button is click?

Log Out And Not Be Able To Use The Back Button
I am devloping a site with a log in function and it works fine, but what I want to make sure that when the user logs out, he/she can not use the back butten and then automatically enter the protected site again, and this is where I am at the moment.
I have tried several no-cache solutions, but they don't work as intended. Users should still be able to go back and forth between pages within the restricted area, and this does not work with no-cache, at least I am not able to make it work.
How do I make sure that using the back button will produce either a expired warning page, or redirect the user to the log in page?
How would this code look? and what page should the code be in?

I used the Macromedia Dreamweaver Login Authentication forms to gain access to my page. The user logs in and logs out just fine. But if they log out, and then click the "BACK" button, then they can return to a secure page that they should have been restricted from.
Does this have to do with Session variables? I'm just confused why they would get access. Do I need to clear something that isn't being cleared?I can upload my code, but I'm not sure what to upload, its all standard MMX stuff.

View Replies View RelatedDisable Back Button
I'm having a problem disabling a back button. Normally what I would do is just throw a history.forward() javascript on the preceding page and be done with it. My problem is that the preceding page can either lead to an error or a confirmation page. If the user produces an error and are taken to the error page, they'll need to be able to click back to correct their mistake. If everything is correct and are taken to the confirmation page, then they shouldn't be allowed to get back.
Has anyone come across this? I've tried setting a session variable when everything is correct but clicking on Back makes the value of the session variable what it was when you originally got to the page.

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:

View Replies View RelatedSelect Box & Back Button
Annoying behavoir from IE6, haven't tested other browsers. Have a select box, onchange event submit the form (it's a date). Data is retrieved for selected date. Everything's wonderful
User clicks the back button, the previous data is displayed, but the current option in the select box is still chosen, so the date that's retrieved doesn't match the date that is selected.
Looks like this is by design, which doesn't make any sense, so I thought of killing the cache. Is this acceptable practice in an ASP app? It's an internal business app running on our intranet if that makes any difference.

1. I'm trying to create an image button that when clicked returns the user to the previous page, however this changes so I've been led to believe that Response.Redirect ("HTTP-REFERER") would be a good command to use. This is to appear on my shopping cart so when a product is added you can click the button and return to the page just left done by 1st line below.
But if the contents of the shopping cart are deleted to zero products it takes you to a "shopping cart is empty" message the button may then need to travel back possibly numerous pages is there an "if page="****.asp"" command so it ignores the page until it finds another url page then goes back to that at the mo the bottom line just takes you to the homepage??
