I searched the forum and got the following code from someone who posted it in 2002. However I can't seem to get it to work in my asp page. Can someone confirm the syntax for me? I would like to try and put it in an include file rather, but need to get it to work first.
Response.ExpiresAbsolute = #1/1/1980#
Response.AddHeader "cache-control", "no-store, must-revalidate, private"
Response.AddHeader "Pragma", "no-cache"
Response.Buffer = True

I have recently changed web hosts, and am suddenly having the problem that IE is displaying cached ASP pages, i.e. displaying data base query results from the first assembly of the asp page. Surely this contravenes the whole principleof ASP as a dynamically generated page. I didnt get the problem with my previous host.
What am I to do about this? If it is browser dependent, how can I be sure that all users have their browsers set correctly. If it is a host problem, it would be good to have some idea what the problem is before contacting them. Or is there something I can do within my asp page to ensure that the current page is the one displayed by the browser?
Is there an effective way to stop pages from being cached?
I've created several websites that have dynamic content and images that are managed by a client. The images are named according to the "id" generated via an Identity column of their corresponding database record (ex: 1058.jpg). The problem occurs when the client tries to change the image.
The client gets understandly confused because the old image is still displayed, due to the browser caching the image. How can I force the browser to stop caching the page/image?
All of the ASP pages already have the following:
<%Response.Expires = -1%>
<meta http-equiv="expires" content="0">
<meta http-equiv="pragma" content="no-cache">
Any ideas?
I am always getting cached pages even contents of the page changed on the server but I am getting old page (data).How to solve this.

View Replies View RelatedWe encountered a very strange problem. We host a web site:
www.[our_site].com and a large number of our users belong to an
organization group with central network control and they can only
access our web site through two headquarter proxy servers: x.x.a.7 and
x.x.b.8, which was set in security dept of the group headquarter. The
web site was working fine till recently when those user accessing via
x.x.a.7 all have problem suddently while those accessing via x.x.b.8
have no problem. The users accessing via x.x.a.7 are directed to wrong
page, very slow response, hang on some page or encounter errors, etc.
If they access the same site via another alias, like
www2.[our_site].com which points to the same web server, they will not
have any problem. They do not have problem to access any other web
sites we tried, including our other web sites hosting in the same site,
even the same server. If the users change their ie setting to use other
public proxy server, they will have no problem to access our site.
Strict security policy are applied to the user site, so we cannot ping,
tracert or do any other network testing from user machine. Since user
has no problem to access any other web site, the headquarter security
department wont handle our case and simply think it is our problem.
This problem is regarding ASP/AJAX. I don't really want to bore you with all the code so i will start off by giving an overview of the problem.
I have an ASP page that places an AJAX request to an ASP page that retrieves a random record from the database, the information returned is then updated into a Div on the original page. The original page has a Refresh link to repeat the procedure and select another random database entry. With me so far?
In firefox this works perfectly, but im having problems in IE. It seems that the ASP page that accesses the database is cached somehow as everytime i use the refresh link it returns the same data. I have used the time() function in the returned data so I can see that it is exactly the same info returned with each refresh.
It seems that the response is being cached and rather than rerunning the script the cache is being returned.
Is there a way to disallow a page from being cached? I'm about to
introduce functionality that will not work properly if the person uses
the 'BACK' button on their browser and would like to ensure that they
cannot. I tried using <% response.expires = -1 %> thinking that it would
work, however it only ensures that another request has to be sent to the
server. Any ideas other than simply giving the user a message NOT to
use the back button?
Here's a link to the functionality. It uses session variables to produce
a dynamic rate quote. (Tip use WDW in the Description/Keyword search).
I am running an ASP file that returns image buttons back to the client. The download on the client side is slow (about 19 small images on the page). I am running on Windows XP SP1 behind ISA server, and the request is coming from an outside IP.
The same application on an NT 4.0 Server works fine. The download time is maybe 3 seconds, versus about 20 seconds for the same exact images. It is behind the same ISA Server.
I want to be able to return to a search results page without having to reload the page after having followed a link from one of the results. Would a search results pages generated by asp be cached, and is it possible to direct the browser to load quickly from the cach rather than slowly from the server.

I have a page that creates a cookie on your computer. at that point it stores login information. Seeing that I am on the administration side and wish to login to accounts without the cookie getting in the way, I create a page to delete the cookie as follows:
Response.Buffer = True
Dim Cookie
For Each Cookie In Response.Cookies
Response.Cookies(Cookie) = "this must be something!"
Response.Cookies(Cookie).Expires = Date() - 1
session.clear
session.Abandon()
Next ' Cookie
For Each Cookie In Response.Cookies
Response.Cookies(Cookie) = "this must be something!"
Response.Cookies(Cookie).Domain = "hazsoft.com"
Response.Cookies(Cookie).Expires = Date() - 1
session.clear
session.Abandon()
Next
This removes the cookie like i desire but, I must first reopen my browser for the cookie to be totally removed. As you can see I have also removed the session variables. Is there a way to remove cookies and session variables, without having to close the browser window?
The code below isn't clearing the cookie and sessions. It is used in my shopping cart to track the user and the items purchased/added to the cart. After making a purchase you are directed to the receipt page (where this code is). If you go back to the main site the items still show in the cart. Any thoughts?
' The below lines clears out the users cookies to allow for additional orders
Response.Cookies("customerid") = ""
(this part seems to work... when clicking refresh the proper error message is displayed etc.)
' The below lines clear session values to avoid duplicate ordering using Refresh
session("cust") = 0
session("cartID") = 0
Is there a way to clear cache using ASP, VBScript or Javascript?
I have created an ASP login page with sessions etc so unregistered members cannot view certain pages, however, when you logout you can still press the back button on the browser toolbar and view the pages, I want to find a way to make those pages expire by clearing the cache or something like that!
Does anyone know how to clear a sites cache with ASP. I have a login script that does not terminate the history when signing out. A user can simply click the back button and get back into the site..

View Replies View RelatedI have three asp pages. The initial page is login.asp, it goes to page hello.asp. And hello.asp goes to page another.asp. If it goes back from hello.asp to login.asp, then in Internet Explorer, clicking on Back, the cache of the page hello.asp has been removed, which is the effect that I want.

I assume it has to do with cache control, but how do I prevent the form from clearing when a user hits the back button? The form I am referring to is my registration page. After the registration is submitted, they are taken to an error handling page. If an error comes up, they are required to hit the back button and correct the mistake.
It seems like for the most part it retains all of the information in the fields, but occasionally it clears it out. How can I prevent this?
How do I clear the data in this field before using the date function.?
<input type="text" size=35 name="DepartCentralDate" value="<%=x_DepartCentral %><%= FormatDateTime(Date, 1) %> <%= FormatDateTime(Now, 3)%>">
How can you clear session variables when a reset button is pressed? I thought I might be able to do something like:
<%
If request.form("Reset") = "Reset" then
Session("variable") = Null
%>
Is this correct, it isn't working right so is there a better way?
was there anyway to clear the data submitted by a form? What i need to do is once the page refreshes, clear the sent data?
View Replies View RelatedI have a form that comes up pre-filled with database results for the values. I'd like to add a button, though, that will clear all fields to start blank if desired.
A standard "reset" button, will only clear input that has been typed in, but won't clear the initial values. Does anyone have a script already that does this or could someone get me started on how I could do this?
I am trying to run and UPDATE, INSERT and DELETE SQL statements to update append and delete data from some tables in access. Here is the low down:
I want to update All of the fields from a table called TEMP into a table called POSTPONED, WHERE the 'postponed' fields = "False"
I want to then go on and clear the records from TEMP that have the field postponed = "false"
And finally i want to again append the remaining data in the TEMP folder into a table called RESULTS.
Does any one know how to do this or what the SQL statements should look like, i have tried writting them, no luck, i have tried generating them in Access but no luck because the ASP is erroring me on them and i dont know what its chatting about!
I have a form that on clicking of the Update button first updates
the specific record in the db, then Inserts if the vMemo field is not
empty. The problem that I'm having is that After updating if you hit
the [F5] key (refresh) it inserts another record ...
I have tried:
1. Clearing the vMemo field after the insert is done (vMemo = "")
2. Setting the value on the form for this field to ""
Neither of these are working. It's not displaying it on the screen
but it is holding it in memory (I guess). Any way to clear this out
after update/insert?
I'm just dipping my toes into server-side scripting.
The Global.asa file seemed really nice, but am I understanding correctly that the application onstart event is fired ONLY when the server is started/re-started or when the FIRST user logs onto an ASP application?
If that's the case, then all the changes I keep making to my Global.asa file are pretty useless, right? (which seems to be the case -- i.e., my pages are not using any of the new information). Code:

View Replies View RelatedI have a bout 5 different pages of which each will contain a form requiring users to complete. These forms are all related as one project. It is necessary that if the user was to only complete the first form they could theoretically quit, come back later (time not dependant) and complete the remaining pages. Therefore I think the best way to do this is to write the values to the database upon each click of the next button. The only other issue with this is that the user will also be receiving a pdf file at the end of the full form submission with all their information inserted into this pdf and finalized. Now. I am aware of pdflib in which I need php but my choice was to do this in asp. What are my options here? Should I combine them, should I draw all the info from the db at the very end with php and then create the pdf, should I use sessions during the entire process
