Answer : Checking server status

This:
req.onreadystatechange=finishLoad(divid);

is NOT what I posted. You are calling finishLoad immediately and assigning its returned value to onreadystatechange, which is wrong. You need to assign a function reference:
req.onreadystatechange=function(){ finishLoad(divid); };
