Thank you for your rapid response. If I may ask what is wrong with it. Because
it does come into this part. It also creates MyListener ant the return
I also have the same line for the http-on-modify-request |if(strcmp(aTopic,
"http-on-modify-request"))| and it seems to work just fine there.
in fact in the observer i have:
if(strcmp(aTopic, "http-on-modify-request"))
{
//here everything works just fine. Can do everything i want.
}
else if(strcmp(aTopic, "http-on-examine-response"))
{
//it comes in here. it says it everything is ok
nsCOMPtr<nsITraceableChannel> traceableChannel = do_QueryInterface(aSubject,
&rv);
MyListener *myListener = new MyListener;
//nsCOMPtry<MyListener> myListener = new MyListener; //i tried this way too
rv = traceableChannel->SetNewListener(myListener,
getter_AddRefs(myListener->mListener)); //I put the nsCOMPtr<nsIStreamListener>
mListener; into the implementation of nsIStreamListener
...
//but the listener doesn't seem to be changed.
}
If something is wrong with strcmp(aTopic, "http-on-modify-request") or
strcmp(aTopic, "http-on-examine-response") i would really appreciate if you
could point me to the right direction.
Really appreciate your help.
