I searched around everywhere on the net, but could not find a simple example
of detecting if cookies are enabled - on server side, and without moving
from one page to another.
This should be a very basic functionality, so I am reluctant to believe that
there's no way to simply test it in a server-side script.
I never really use cookies but I need to make sure that browsers have cookies enabled for cookies and ASP session variables. There are not javascript cookies only. I'm using the following code but it's just not working out. Even if cookies are cleared and off in my browser, it still registers that the cookie I attempt to set is successful. With cookies disabled I expect that no cookies should be set. It seems like it might even be set just for the life of the Sub but I can't really tell.
Anyone have a good way to do this or know how to modify mine?
Code:
Sub checkCookiesOn Response.Cookies("ASPLPCookieCheck") = "True" If Request.Cookies("ASPLPCookieCheck") <> "True" Then Response.Redirect("/error.asp?error=cookies") Else 'Request.Cookies.Remove("ASPLPCookieCheck") Response.Cookies("ASPLPCookieCheck").Expires= #September 12,2000# End If
It is possible to check via ASP whether cookies are enabled for a person's web browser and based on this check send him to another page which does not support cookies (ie login?)?
I was thinking about an easy to determine if cookies are set or not in ASP. I began thinking about how the Session ID is dependent upon a cookie - right?
Well, I disabled cookies in Firefox and then loaded a webpage that displayed Session.SessionID. Viola, I got one! And then, I reloaded the page. And then, I noticed that the SessionID incremented by one!
This still isn't yet a one-page method of detecting if cookies are enabled or not (like BrowserHawk does), but are there any possibilities here?
I would like to kinda have things happen if javascript is enabled in the browser, or if it isn't then do some other things. For example, if I know javascript is enabled, I could bring a popup window, etc. but if it isn't, then I could just provide a link instead.
I am writing an application in ASP which needs to decide at server side while the ASP code is executing whether the cookie is enabled/disabled at the client browser or not.
I do got the code which runs accurately when the IP Address is given of the server. It does not work when I access the web server(local development server) by it's name.
Please note that the code below sometimes does not work even when the IP Address was given to access the web site.
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.
Is it possible for a user to enable permanent cookies but disable session cookies.....this seems like a contradition yet this is what I appear to be reading in online articles?
I m creating a cookies in my application and it work properly but i can't see the cookies where it will sotred i checked the cookies folder but i didn't find that I want to create a cookies file as the other web site create and store where other cookies will stored in Cookies folder or Temprory Internet files folder eg:1. arvind@google.co[1].txt this stored in cookies folder 2. arvind@msn[2].txt ....
Is there a way for asp to know what url is in the address window? I have a function that is included in every one of my pages and I want it to write out different things depending on the page the visitor is on.
Can anyone tell me how to detect a ip address behind a router? I know that using ASP, we can detect the actual ip and the proxy ip, but what if the visitor is using a router that dynamically assigns a ip.
I'm working on an app to upload pictures to my Web page. As part of it, I need to know the dimensions of the images - how many pixels wide by how many pixels high. Is there any way, as part of the upload or immediately after, that I can detect that?
Also, though the solution isn't exactly appropriate to this NG, I would also accept a client-side solution to this problem.
Normally I would do something like if request.form("submitbutton.x") <"" then .... end if
But I found a problem when the browser uses the 'alt text' instead of the image (when the image is not found, or if the browser is not displaying graphics, etc. How do you detect that? or should I?
I am working with a bunch of old code so I can really restructure the includes, otherwise I guess I could change all the #include statements to #include-once. Anyway, If I have a file with a class like this:
Class myClass end class
I get a "name redefined" error. I've been seeing these and indeed from goolge searches, it's because the file is somehow included more than once. This problem doesn't occur for functions and the old code bases just used functions whereas I would like to add some classes. In C you used to be able to detect that at the top of the file and not included the rest of the file if it is allready included. I just want to at least detect it so I don't redeclare the class.
How can I get the url of a page in asp and detect if there are no variables appended to the end? Would I somehow get the address and do an instr for the ? character? Code:
Could anyone show me a tutorial or like show me a script in asp that can detect to see if the mysql backend is working? And if it isn't then to display a message that says something like "out of luck."
Is there a way whereby i can detect where the user came from?
For example:
if this user came from www.mywebsite.com/a.asp theni will redirect him to c.asp but if he came from www.mywebsite.com/b.asp then i will redirect him to d.asp
I need to add in some specific browser detection in my ASP to identify Mac IE5 running OSX - is there any wahy of identifying this config alone - and not just identifying all Mac IE5s? If you have OSX Mac IE 5, please visit this page which will give your User Agent string.
The delete method of the FileSystemObject.FileObject does not return a result. If permissions disallow deletion, it will not raise an error. Conversely, if the delete method does succeed, a call to FileExists directly afterward may return true because the system hasn't updated yet (or whatever actually goes on). Is there any way to accurately check the result of a deletion?
I've been working on this wysiwyg web editor. The editor lets you upload images. Only .jpg, .gif and .png files are allowed. Now I should be able to detect if the uploaded .jpg image is in RGB or CMYK mode. Only RGB images should be allowed. Can this be done with ASP?
I'm trying to write an ASP interface that mimiks a .Net datagrid control. I'm having a problem when I'm in the middle of an Edit, Update, or a New Record.
If the user hits the wrong button, the program grabs the values in the textboxes using the request.form() and then redisplays them in the textboxes when the records table gets written back out to the page. This works fine as long as the form is submitted.
If it's just a page refresh (F5), the program doesn't get the latest changes to the textboxes and displays either a blank or whatever was in there the last time the form was submitted. Anybody got any ideas?
Im writting an asp app that tracks the users scores and info (its a training app) to a access database, ive disabled the ie toolbars and everthing so the user must use my nav buttons so i can track what pages they have been to. My problem is if the user closes IE with the close button [X], is there a way i can redirect them to my close database and save results page, i cant use the unload event as this is trggered every time the use goes to the next page.
This is fine for displaying the text, but the text contains links which are currently just being displayed as text. I'd like them to display as hyperlinks that will open in new windows when clicked upon. so basically I need some ASP code to detect text starting with http:// or www.etc and automatically make them into hyperlinks.
