Creating Cookies From Querystrings
I am able to create and read cookies, however, I have to *create cookies from querystrings* (I cannot do this from form values, because the response page *redirects to the page I am working on, so there is no direct way to use Request.Form("var")*
Anyway, when I create the cookie, and remove the querystrings, of course, the cookie no longer works.
How do I take querystring values and turn them into cookies, such as page.asp?name=dave
to create a cookie 'username' with value 'dave'
and when they visit just plain page.asp, it remembers the value 'dave'
What can I do to get it to work?

I've noticed a strange problem with setting cookies in ASP when the
cookie name you're setting exists in the querystring. The company I
work for has many partner sites who link to our site like this:
www.mycompany.com/partner.asp?PartnerID=??? The partner.asp page then
sets a cookie called PartnerID containing the value from the
querystring.
We have noticed, however, that if the partner calls the partner.asp
page and alters the capitalization of 'PartnerID' then another cookie
gets set which takes the capitalization of 'PartnerID' from the
querystring. All of the other asp pages in the site then seem to read
the first cookie set and thus it appears that the 'wrong' partner
settings are being used.
Has anyone experienced this problem before? Unfortunately altering the
cookie or querystring names would be a non-trivial task so this is not
an option at the moment.

In my Session_OnStart in Global.asa, I am setting some cookies. One
of them, I set as follows:
dim UserID
UserID = Request.ServerVariables("LOGON_USER")
Response.Cookies("User")("ID") = UCASE(UserID)
When I immediately log the cookie value retrieved from
Request.Cookies("User")("ID") into the Windows Event Log, I get the
correct value. However, when I try to retrieve the cookie on the home
page of my application using the same code,
Request.Cookies("User")("ID"), it either cannot find the cookie or
cannot read the value. I am retrieving the cookie before all HTML
headers are written. It is my first statement on the page after
Option Explicit. I have even compared the session IDs. The SessionID
created in the Session_OnStart is the same value as the SessionID on
the home page.
I have read that the Session_OnStart only has access to the
Application, Session and Request objects. It does not explicitly say
that it does not have access to the Response object. Also, I was even
able to use Response.Write's in Global.asa to print out the values
although it looked like it had also stopped the session after I did
so. Cookies are definitely enabled on my machine. I have even tried
setting the session cookie's expiration to be persistent for a few
days to see if it was perhaps expiring before I was able to read it
but this did not work either.
Is there something preventing cookies to be created in Global.asa in
the Session_OnStart sub? Is the Response object not available???
Please let me know if anyone else has had this problem or solution.

I need to read a querystring from a frameset, actually its the parent of the frameset. The page that will do the reading is not actually one of the pages on the frameset but a pop-up window spawned by a frame in the frameset.
Using javascript I would use the window.parent.parent.location.search property but how do I do this with asp? is there an equivalent of this?

I've been building an Intranet app; and have used hidden fields exclusively to pass one or two things from one page to another.
However, now I have reached a point where I may have an email sent to a co-worker, and they want to be able to click on a link in the email to take them directly to the info about that item. While previously, I had been able to get to that item by typing an identifying number in a text box and clicking a submit button, that won't be possible with a link in an email. I guess I will have to use a querystring.
I am not sure how the querystring thing works, but it looks pretty easy on first glance. Is there a tutorial, a really basic one, showing how to use the querystring? Do I have to use the post method now?

I currently have been using something like this:
Code:
response.redirect(request.querystring("page"))
It worked fine because I didn't need to pass on any other values from the querystrings. But now, I need something that will redirect the page and pass all querystring values. I tried this:
Code:
response.redirect(request.querystring("page") & "&" & request.querystring)
But it brings me to something like this:
http://www.site.com/thepage.asp&page%3D/thepage.asp&id%3D7
instead of what I would like for it to say:
http://www.site.com/thepage.asp&page=/thepage.asp&id=7
Now.... I know that I could have written:
Code:
response.redirect(request.querystring("page") & "&id=" & request.querystring("id"))
But that won't work because I actually have many querystrings and I won't know which ones are used, etc. I want it to just transfer all the querystring data.
Oh, and if the redirect could take out the "page" querystring.. that would be great. Because I don't need it.. it is only used to know what page to go to. I just need to keep all the other querystrings.

Can ASP use valueless or variable less QueryStrings like this:
http://yoursite.com/forum/activate.asp?985486. (Not a real link).
I would also like to know if it can use addresses like this:

I would like to know for some work I am doing.

I can parse my querystring just fine. But one thing that I can't seem to get working is displaying some of the data in a select box. Example:
?id=1&type=yy&equip_id0=t1&mac_addr=123&mac_addr1=456
&equip_id1=t2&mac_addr3=789....
I can populate the id and type values in my form fields just fine but equip_id and mac_addr will never be consistent. Certain case will have only one equip_id and one mac_addr value and in other case I will have equip_id0 thru equip_id20 and same with mac_addr. I simply want to parse whatever response I get and display those equip_id and mac_addr values dynamically in a select box. Is that possible?

Whenever I click on a link (on the shoppingcart site I'm developing) that contains a querystring with the category name and an anchor name (whatever the name of the '#' bit in the URL is), SQL retrieves the category name from the querystring, filters out the appropriate information on the products and the page jumps down to the anchor link.
Once the customer clicks on a product, the processing page is meant to redirect, via the server.redirect command, back to the products page with a querystring identical to the initial filtering one (with the anchor name attached), thus teh customer is back to the same product that he clicked on, without having to scroll down every few seconds to add more of the same product.
However, even though the querystring sent by the response.redirect command is identical, the ASP code can't seperate it again properly and thus the SQL statement shows nothing, as the ASP coding thinks that the info following (and including) the # is apart of the 'category' part of the querystring.

I started noticing some page errors in my web application. All
of the erroring clients where using Windows XP - MSIE 6.0. It seems these
clients were passing the bookmark (fragment identifier) portion of the URL
to the server.
For example, with the following URL:
http://testsite.com/page.aspx?myquery=test#bookmark
The browser *should* send a request for:
http://testsite.com/page.aspx?myquery=test
However, these clients were sending the entire URL as the request. Thus, my
querystring parameter "myquery" had the unexpected value of "test#bookmark".
Has anyone else noticed this behavior? Perhaps it is related to the
download.ject patch (released July 2). I have yet to recieve a response to
this message, which was posted one week ago in two other newsgroups.

I am creating a user tracking app that tracks a user one of two ways...
1)First Method is cookies
2)Second Method MS SQL DB
I first check if the users browser accepts cookies if not I go to the db. If the user accepts cookies then I check for a specific crumb if it does not have the value I am looking for I kill it and rewrite it. This is working fine (im in the middle of testing it). The problem is I decieded to test the script with NN7 and not turn cookies off but block cookies from my site and all fell apart. The condition that I have set (detect if cookies are enabled) does not stop the script from trying to set a Session Variable because the browser accepts cookies and to keep a long story short it goes into an infinite loop because the script is looking for a Session value and Its not being stopped becaues the script thinks its alright to write cookies! Is there a way to detect if a user has your sites cookies blocked? This is important because Server.CreateObject("MSWC.BrowserType") will return .Cookies = True and you will not know that your script is not executing properly because a user has your sites cookies blocked but excepts them elsewhere...

I've built a website which requires a user to log-in to access the site. I have already built a page that enters their details into a db (register.asp), and another page where the user enters their email address (the log-in ID) to actually log-in (login.asp).
How can I use a cookie to automatically log a user in??
More specifically, what are the commands to set a cookie (upon successful registration) and access it (upon re-logging in)?

Hey i've spent the last few hours trying to work this problem out about cookies.
When a user logs in to the site the login.asp page checks the database to see the personal page that the user re directs to e.g if bob brown logged in he would be redirected to bob.brown.asp. This is stored in a field in the database table along with the username and password.
i would like to put a cookie onto the users computer that remembers the url they were redirected to so when they press the main page button it would look for the cookie and see what url they are meant to be redirected to and take them there
My current login system is this ....

I'm trying to load up a page through my asp page and get the cookie from that page so that I can use it later on when it needs to have it to access other parts of the site.
Basically the asp page is going to act like a browser and store the cookie from the other site, then send that cookie back when the asp page goes back to the other site again.
The problem is, I can only seem to access my own cookie. I didn't run into this problem when I was doing a similar thing inside my .cs scripts that were run by the server, as I suppose they were not coming from the actual domain that my page is running on (and thus, wasn't getting everything trampled by local cookies).
Is this possible, or should I just give up on it now?

im building a site for a few doctors surgeries. the user is able to see what appointments are available and then book that date/time. i have a table (in my db) of dates/times and a checkbox to say whether the time has been booked or not (and display only times that havnt been booked). i was going to have the user add the time to a "cart" and then check the "booked" checkbox in my db when theyve paid for that appointment. but if i have lots of people looking at the site at the same time, then they may be able to see times that are just about to be booked. i think a better way is to have the date/time stuffed into a cookie which expires after 5 minutes. so when a user adds a time to their "cart", it will say something like: "this time will expire in 5 minutes until you book it or re-add it to your cart". does that make sense?
how can i do this with server-cide cookies (im using jscript)? can anyone think of a better way to do this?

Else
