I always thought that Ajax was purely a client-side thing (Asynchronous Javascript etc..). Maybe this is only a name coincidence ? From a server point of view, there should not be anything special distinguishing Ajax-triggered requests from others, not so ? Of course, perhaps one has one of these nifty real-time Ajax-driven popups which poll the server every 0.1 second for an update to some graphic gimmick.. Which would of course provide some clue as to a gradual slowdown of some webserver, as the poor thing struggles to keep up. Mere loose and unfounded speculation of course, on the base of at best flimsy evidence.

I was looking at Wicket in Wikipedia, That sir, is because you are not an Englishman. However, I can assure you, that we are very familiar with the wicket. What ho'! Well exactly. The only familiarity I previously had with the word wicket, was as some bit of wood carefully balanced on top of two other bits of wood, with some white-attired gentleman armed with another (wider) piece of wood in front, seemingly very anxious not to let another bloke viciously toss the first bit of wood off the second ones by means of something looking like a bigger golf ball. And of course as a term in the mysterious kind of point-scoring ritual that goes with the same, along with other keywords like inning, not outs and such. So, in my mind - before I consulted Wikipedia - I had this picture of some kind of graphic browser applet, mostly popular in the UK and Indian markets, which one could use to superimpose the lastest results of such games worldwide upon one's professional workspace, with real-time updates. But then, from previous experience watching the game on TV, I still could not quite figure out how even the real-time updates of 10 simultaneous tournaments for tens of users, could possibly overwhelm a Tomcat server, given the apparent pace of said game. So that is why I checked Wikipedia, to see if my understanding was sufficient. And to my utter relief, I realised it wasn't, and that the word wicket also seemed to cover some client-server software architectural feature, where indeed data may be exchanged by means of Ajax calls and such, but the data in question could be related to faster-moving matters, thus validating my initial suspicions, after a fashion. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
