Problem Description
Hi everybody.
Exception (3) occurs on the standard example every time when Safari makes sudden HNAP calls(Home Network Administration Protocol) on the server. These HTTP calls made by Safari are a little bit hectic and sometimes we need to wait several minutes before receiving them. Chrome doesn't seem to send these kind a HTTP calls.
Thanks in advance for the help.
