Question:

How do you use webbatch to read and set cookies from the client?

Answer:

Setting Cookies

Cookies are set in the header portion of a html page returned to the user.

	WebOut('Content-type: text/html', 1)  ; Note only 1 LF here
        WebOut('Set-Cookie: useridcode=Fred;',2) ; Note 2 LF's here to stop header
	WebOutFile('c:\home\some.html')

The above code will set a cookie "useridcode" to value "Fred"

Reading Cookies

Do a:

http://your.computer.com/webcgi/webbatch.exe?dumpinputdata 

and see how it shows up there. Then a WebDatData ought to be able to pick it up.

Using the example above

   useridcode=WebDatData("useridcode")

Should return the value "Fred"

In addition to the suggestion of looking at the dumpinputdata command, you might want to take a look at the home of weber files; there are a few (somewhat crude, but workable) verbs that handle cookies, including {setcookie} and {ifcookie}. Click on the name of the verb for its source code and you'll see how I did it.

The WebBatch website is created using weber files and has some examples of how they work (see the "how was this done" button).
