I am running IIS5.1. I am invoking an ASP page in ther server continously from the HTML Page, to update some contents of the html page. The ASP page seem to run from the cache sometimes(Not Always). I tried to give the following header to my ASP file.
Response.Expires = 0
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
still the contents seem to get cached. how can i avoid this ?
Currently i did 2 pages
form and action pages, where form will have 2 inputs, and action page will insert the data into database.
but the i have tested once i keep refresh the action page, the data will be inserted again and again, anyone know how can i control this matter and avoid sql injection?
I've managed to build my first site is ASP, it has a basic shopping cart and search function. I'm having a bit of a problem with pages being cached messing up the display of the shopping cart.
What happens when I add in a product to the cart is the page sends the required information via a form to another processing page, this page then adds the items to the shopping cart which is an access database and then re-directs you back to the page you were on when you clicked the add to cart button. This re-loading of the page also updates a small shopping list I have on the right hand side of the page.
if i click the back button on the browser the shopping list now looks like its empty, if I press the refresh button it fixes the shopping list to what it should be. I've tried a few things I found on the internet and none of them worked anybody know how to get round this?
Is there a way to cache an ASP page on the servers memory for a certain amount of time?

View Replies View RelatedI wish to avoid caching asp pages at the user end . Currently I have declared Response.Expires=0 at the top of my asp page. I have also used the following meta tags
to prevent client side caching:
<meta HTTP-EQUI="PRAGMA" CONTENT="NO-CACHE"></meta>
but still the pages are cached at the client side.
I'm doing a banner ad management system and am storing about 400 banners in my database. I need to pull them all and then sort them by weight and pull randomly from that sort to populate the page with banners (6 per page).
My problem is that pulling 400 banners and sorting them on every page is obviously a performance issue.
Does ASP have any sort of session or page caching capability that would allow me to cache these results and then update the cache anytime something changes with the banner database tables?
how to elaborate this problem that i m facing. ok, let say ..i have a URL wit id number such as www.abc.com/memberpage.asp?memberid=12.
when i add the symbol ' at the end of the url (like that:www.abc.com/memberpage.asp?memberid=12'), and enter, it will display error for my page.
But when i try to put a ' at this web page here, it will not display any error, how can i do this with ASP languagE?how can i avoid it using ASP language ?
I'm getting crazy with this. You know that when you install office in your computer it install a plugin for Internet Explorer so when you click in a link to any office document it opens the document inside the explorer instead of asking to save it as normal files.
Do you know how to make internet explorer ask to save the document with HTML or ASP or Javascript?I know that i can disable this option in Internet Explorer options but i don't want to make people do this.I don't want to zip the file neither.
When I use funtion--CreateObject to create an instance of Msword in the client script,

Is there a way to avoid On Error Resume Next for:
cnn.Open strCon
SQL = "EXEC Customer @txtEmail='" & email_address & "'"
set rs = cnn.execute(SQL)
'On error resume next
rs("email_address")
'// This record does not exist thus throwing up an error. I could use On
Error to resume and then do this
'// If rs.eof or rs.bof
'//
.....But I hate this convention as I find debugging a problem. Is there a
better way?
I have a table with "title" field set to unique In PHP I can do this following code to check whether the same input already exist or not:
$query = "insert into table (title) values ('".$title."')";
if (mysql_query($query)) {
echo "Title already exist!!"
} else {
echo "New Title saved!!"
}
My question, is there some similar method to do above operation in ASP? Code:

I am working with website in which a user can login and then submit some forms. I want the user to avoid re-submitting the same form twice when he uses the browser refresh or when he goes to another page and then comes back to that same page using the browser back button.
I know of two solutions:
1. Redirect to a different page after form submission - The problem with this approach is that the website has many forms. So redirecting each form to a different one is not a very feasible solution.
2. A token can be stored in session (or somewhere) after each form submission. These tokens can be verified if the form is being resubmitted - The problem with this approach is that the user can submit
one form only once. I want the user to be able to submit the same form multiple times, provided with differetn data.
Is there a suitable solution where a form with same data is submitted only once, but there is no such restriction with different data?
Can the ASP request object be cleared after form submission, so even when refresh button is pressed, Request.Form elements dont have any data? (Storing ALL the information filled in each form during that session and then comparing for resubmit is not a clean solution I think??).

Just recently we have encountered a weird problem with our
webserver...running IIS 5 and W2000 SP4
When testing an ASP page, if you get an error of some sort in your browser,
when you go into the code and fix the problem, save the changes, when you
refresh the page, the error stays there, even though the code is correct.
The problem is not fixed until you rename the page, and the open it in your
browser to work fine??
We have a website that reads data from Oracle and creates an XML file. Then
the site uses that file to access the info faster. On IIS5 we have no
problems, but on IIS6 we seem to have some caching issuses. This deals with
the Worker Processes. By default, there is only 1 Worker Process that gets
recycled after 1700 minutes or so. The problem is, that we will select some
data from the screen, which opens up another window to update the info. We
walk through the update process and change some data and it updates the page
fine. We can even check the XML file and it is changed, but if you choose to
go back into that data, the dropdowns will reflect whatever was initially in
the XML not the changes. If I increase the number of Worker Processes and
shorten their recycle time, this doesn't seem to be a problem, but for every
request I am generating a 25M file on the server that eventually gets
recycled. I don't want to load up the memory with useless files, but I want
our application to reflect the correct data. I really need to do this without
affecting any other possible web apps that may be on the box.
Never had this problem before, but my SSI's in an ASP page are caching. I don't think ASP has anything to do with it mind you. I think it's a server issue (I've never really used this hosting company before).
Is there any way (ASP or otherwise) that anyone knows of stopping a web server caching your SSI's. It's VERY annoying!
We have an IIS cluster running an ASP website. We installed the patch listed under Q239703 that allows IIS to recognize script updates and appriately not cache those ASP pages. However, since we made this change, any office documents that a user tries to download exhibit the problem listed in Q316431. We do not use any of the caching commands listed in this article (Pragma: no-cache OR
Cache-control: no-cache,max-age=0,must-revalidate). In fact we do not have anything set in the code at all with regards to caching, and the only this i can come up with is the change we made from Q239703, which is needed to stop IIS from caching ASP based pages
We are attempting to cache asp web pages in our isa server from the local county property appraiser web site to speed up access, with a 60 minute TTL (time to live).
This doesn't seem to be working - at least the pages aren't coming up any faster. Is there anything in asp that could be preventing the pages from being cached locally?
What is the best way to cache images, and stylesheets on an asp site? I currently use a .asp extension on all my pages because I use include statements to keep certain parts of my layout the same(menu, logo, footer). I have read that asp doesn't cache pages by default, and that they are processed everytime on the server. This can eat bandwidth up pretty fast.
There also seems to be a few ways to cache a page (response.expires, cache-control, public, using meta tags, and a few more).
