comet

I saw a video of Google I/O and found an example of GWT UI being very consistent between clients. Which you can save, add, drag and drop in almost real time between clients. I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information? Thank you very much OK, I think what you are looking for is known under the names Comet, Server Push, Reverse Ajax (to name a few - they all mean the same, might be helpful when doing research on this subject). In short, it

I'm looking for the 'way to go' (i.e. the most efficient, most used, general accepted way) when it comes to the reloading of data from a web server to a front end. In the end application, I will have several output fields where data has to be written to, for example like this: The data streams will be different from each other in the end application. The lines will have to be reloaded with fresh, up to date data from the server. I have been thinking of using Ajax requests to update like every second, but there has to be an other way to do this. Ajax requests will cause a lot data traffic. Also

Is there a real solution for COMET AND PHP combination? Basically, I've come to a point that I need to update a user home page periodically whenever there is new data in the database. As far as I understand, I need to open a persistent connection between my server and my clients browsers to update the contents of their home page as soon as new info. available without dedicating a lot of resources but I had no luck finding anything clear about this issue. I read many articles suggests that PHP is not a good language to implement COMET. My web application is completely programmed in PHP and I

Client request web page from server. Clent then requests for extra calculations to be done; server performs series of calculations and sends partial results as soon as they are available (text format, each line contains separate full item). Client updates web page (with JavaScript and DOM) using information provided by server. This seems to fit HTTP Streaming ( current version) pattern from Ajaxpatterns site. The question is how to do it in cross-browser (browser agnostic) way, preferably without using JavaScript frameworks, or using some lightweight framework like jQuery. The problem begins

see also " WCF push to client through firewall " I need to have a WCF client that connect to a WCF server, then when some of the data changes on the server the clients need to update its display. As there is likely to be a firewall between the clients and the server. All communications must be over HTTP The server can not make an (physical) outgoing call to the client. As I am writing both the client and the server I do not need to limit the solution to only using soap etc. I am looking for built in surport for " long polling " / " Comet " etc Thanks for the most informative answer from Drew

I'm going to be implementing Comet in Python (even though I hear good things about erlycomet I'm not thrilled about supporting an Erlang-based web server in addition to everything else in our back end). I've found several possibilities: Diesel Tornado Twisted-comet Orbited (uses twisted) (there are also some other choices that interface with Java servers, but I'm not interested in those) Can somebody make a recommendation among these implementations, considering performance, community, and ease of implementation? I am personally using Orbited, both because I am already using Twisted and
