The answer to that is going to depend on how your web based HMI will work. I've designed one that you can create whatever you want as part of the web page and manipulate it (rotate, change colour, etc.). It comes with a set of common symbols, but you can make your own easily enough and manipulate them using one of the standard methods.
Most 'web based' HMIs however are actually a collection of Java (or ActiveX) applets. That means that each 'symbol' is actually an independent program that happens to run inside the web browser. In that case, you have to live with whatever they happen to give you, and they typically all have to be designed to work together so you can't just mix and match them.
In either case, a web based HMI needs some sort of server. It needs a web server to serve up the web page (and other files, including the Java/ActiveX applets). It also needs a communications server to act a a middleman between your web browser and the PLC/SCADA/whatever. Both functions typically need to be built into the same piece of software (because of the way that newer web browsers work).
So, what are you looking for? Do you have an existing web based HMI and are just looking to expand the Java (ActiveX) applet collection? Does it need to work with a specific HMI/SCADA system? What sort of equipment does it need to be able to talk with, and using what protocol? Or do you have nothing at present and are looking around to see what is available?
