Working with cookies

Download source files - 3 Kb

Overview

This is a small ASP (Microsoft Active Server Pages) application that implements basically work with cookies.
The project has next main-functionality:

• read cookies
• write cookies
• set expired date for cookies

The page contains a help that make your work easy with the project. The sample is ready to use.

Details

The project has three important parts:

1. Test if the client browser support cookies.

   For that I use the Browser Capabilities component (“MSWC.BrowserType”)

   	set objBrowserCapabilities = server.CreateObject("MSWC.BrowserType")
   	
   	' ...
   	
   	blnSupportCookies = objBrowserCapabilities.cookies
   	
   	' ...
   

2. Read and display cookies

   For that I use the Request.Cookies collection. (See the ASP built-in objects.)

3. Write cookies to client browser

   For that I use the Response.Cookies collection. (See the ASP built-in objects.)

Usage

    The cookies have two forms:(See http://www.microsoft.com/info/cookies.htm)

• normal cookies
• dictionary cookies

If you want write a normal cookie then specify a value in the Cookie Name field (this field is required) and a value in the Cookie Value field. If you want to write a dictionary cookie first you must type the number of keys (must be great 0) and then click 'Write cookie dictionary'. The page is then setup with your options and you can type values for your cookie dictionary. After you put the values in fields click 'Submit'. The cookie is written to the browser and is automatically read and displayed on the page.

If you don’t set an expire value then your cookie lifetime will end after you shut down the current session. To extend yours cookies lifetime, you must set the Date and Hour values.

I agree with Tom! This code is worthless Brian 12:54 7 Feb '00   First: This article offers nothing more than excert from MSDN. Second: YOU DON'T TEST COOKIES BY BROWSER TYPE! They should only be tested by redirect. ( I would not even trust ASPSessionID ) Look at 15seconds. Sign In·View Thread·PermaLink Re: I agree with Tom!

You are a hidden user? Why you not publish your correct email addres? BE HONEST !!

Most of my code is mixture of high performance ISAPI + COM + ASP ( don't care for cookies, my code will work either way ).

You maintain this? 2) Ok, it is your choice. 3) Such, I don’t play ASP games. I’m working with USA Company, which develops a software product that manages Microsoft Exchange Server. I’m not beginner in ASP, and my code is a mixture of COM + ASP. This is my first project that I post into a free-code site, and I was worked 4 hours at it. I want test these free-code sites. I hope we have a great collaboration in the future… Thanks, Iulian ….

Sign In·View Thread·PermaLink Cookies Test not "safe" Tom Wellige 22:05 3 Feb '00   Hi Iulian. With using server.CreateObject("MSWC.BrowserType") blnSupportCookies = objBrowserCapabilities.cookies you only know that the browser principaly support cookies but you don't know if they are enabled or not. I would suggest additionaly testing e.g. via a session varaible. If IIS is able to place the sessionid in a cookie and therefor be able to read the session variable on a redirected page again, the cookies are realy available. Kindest regards, Tom. Sign In·View Thread·PermaLink Re: Cookies Test not Uwe Keim 3:46 6 Feb '00   No, you have to test it in a real cookie, not just a session. Why use a session, when you want to test for a cookie? Set a cookie on one page and read it on another to find out, whether cookies are allowed Sign In·View Thread·PermaLink 3.50/5 (2 votes) Re: Cookies Test not Tom Wellige 22:12 6 Feb '00   >No, you have to test it in a real cookie, not just a >session. If cookies are disabled you won't get the value you have written into a session variable back when asking for it on another page. I agree that writing directly into a cookie is more abvious to get the wanted result, but using session variables will work also. Sign In·View Thread·PermaLink Re: Cookies Test not Uwe Keim 22:23 6 Feb '00   No again Since IE5 distinguishes between Enabling/Disabling of temporary Cookies (i.e. Sessions) and permanent Cookies (i.e. Cookies), you won't have the same result Sign In·View Thread·PermaLink Re: Cookies Test not Tom Wellige 23:17 6 Feb '00   Ok, this point goes to you :- Sign In·View Thread·PermaLink Re: Cookies Test not Iulian Iuga 22:22 6 Feb '00   Before, thanks for your interesting about my code. So, you was tested the project with a browser that has disabling cookies? Please do it with IE and Netscape. The result is, the cookie was write and after read the cookie was deleted. So, I was focused to the cookies not to browser capabilities … . Thanks, Iulian Iuga. Sign In·View Thread·PermaLink 1.00/5 (1 vote)
