A Cookie Parser in Java

	Java Programming Resources home.		Core Web Programming home.

Following is the source code for CookieParser and all supporting Java classes. This class parses the "Cookie:" HTTP request line and makes individual URL-decoded cookie values available in a lookup table with the name as a key. It supports having multiple values associated with the same name.

• CookieParser.java -- the top-level parser.
• CgiParser.java -- the underlying parser.
• LookupTable.java -- a data structure used to store the results.
• URLDecoder.java -- the decoder of individual values.
• StringVector.java -- an internal data structure.
• CssTest.java. An example of the use of CookieParser. This creates an input page where the user can select cascading style sheet values, displays the result, and "remembers" the choices to use as the default next time. Uses CssChoices.java internally, plus needs a simple shell script to act as a CGI interface (Unix; use a similar .bat file on Windows).
• CssTest -- An on-line demonstration of the cookie parser in action.
