What I need info. on is specifically in relation to clients that would conform to Wireless Application Protocol(WAP)? Most of the microbrowsers that are out there seem to be the type that simply display cached files that are downloaded a priori !! So I guess what I really need to know is whether implementing a WAP client would be anything like doing the same for an HTTP client. Where can I look for additional information? I am of course talking in the context of PDAs, because I know there are several cellular phone vendors that have integrated WAP clients into their phones. Hope you'll be able to help me out a little more - I really appreciate it.
