asp button click handler

[Peter Kirk]

Hi

if I have an asp:button with runat=server, when it is clicked the code
behind (onclick handler) is called. If the onclick function is a long time
running, does the button wait until the handler is finished until it can be
clicked again? Or can I risk that a user can cause two executions of my
onclick handler to be executing at the same time?

Thanks,
Peter

I do a lot of updates in a database when the user clicks the button. It
could take maybe 1 - 1½ seconds before completing.

But sometimes I am seeing double updates if I click rapidly many times on
the button. It appears that Internet Explorer can send mulitple requests
from the same browser "simultaneously". That is, it does not wait for the
server to complete the onclick handler before allowing the handler to fire
again.

client first, then server sequentially. why do you have this long
processing
on the client?
