ajax - using multiple update panels in asp.net -

Hello I doubt it, I use four different update panels, which uses a timer similar to the trigger Now my questions are this.

1) Will 4 update panel create 4 separate HTTP requests on the server? 2) I am using 4 different panels because the controls are located in different parts of the page, is there a way to put them in the same update panel? 3) Is this a good coding practice?

For simplicity, one of you can update the timer's updated panel, and always for other Set the updatemode of three. When there is an update for the first time, the first three will be updated.

This is an interesting scenario; I am not 100% sure that the four requests are theoretically possible.
