HTHostEventimeout: How do u cancle a timer

On the HostEventTimeout, I have a general question
 
I have a similar application that launches a request recursively. What I
do notice is that the timer that is started for a request (or rather the
host) is not cancelled when the request is complete. It times out after
the pre determined 30 seconds. IF we had launched another request then a
new timer is started.
 
My questions is : shouldn't the old timer (with the first request) be
cancelled. I can see that it times out at the end of 30 seconds and
tries to execute the call back function. If there is a method to do that
can someone please point me to it. I would imagine that the library
should take care of this automatically
 
Thanks Raj

	Hi All,
	 
	    I have written a piece of code something like this and I am
calling the function xrayhttpget after a fixed time interval
repeatetively .But I have encountered a problem in this
	Suppose I give a valid uri of some html document and as I said
my program logic will continuosly loop and try to fetch this document in
each iteration .Also I have specified the 
	time gap between the successive requests is 3 seconds then
during the second iteration my program gives segmentaion fault and it
occurs due to the HTHost_setEventTimeout(3000);
	call in the code.Could anyone explain me why this could occur?
	 
	Thanks
	Sandesh
