We configure an environment and client component(named PivotGrid)
accesses AS via HTTP Login which is required from customer. MSOLAP.asp
only request when PivotGrid send query command if both IIS and AS are
in the same machine.

When we try to seperate IIS and AS in different machine, from the IIS
log file, we found, when PivotGrid trying to use HTTP login, it calls
the file MSOLAP.asp and just loops calling the file 20-50 times per
second even if PivotGrid don't sumbit any command. This continues until
IE is closed by user.

Could anyone can explain to me why occured such problem?
