Is it possible to use GetAsync from another Thread than main? Or is it that your design logic is not for that?   I try to Get a document every second from another Thread and it works fine, but GetAsync does nothing.   Get do this: 09:23:15:125am|State = httpNotConnected 09:23:15:126am|Login www.tuenvio.cu 09:23:15:126am|State = httpDnsLookup 09:23:15:201am|Socket DNS Lookup Done - 181.225.247.68,181.225.247.69 09:23:15:201am|Alternate Address: 181.225.247.68 09:23:15:201am|State = httpDnsLookupDone 09:23:15:201am|connect to 181.225.247.68/443 09:23:15:201am|03203960 Socket handle created handle=1144 09:23:15:201am|TWSocket will connect to 181.225.247.68:443 09:23:15:338am|SessionConnected, error=0 to 181.225.247.68:443 ... GetAsync only this: 09:35:46:791am|State = httpNotConnected 09:35:46:791am|Login www.tuenvio.cu 09:35:46:791am|State = httpDnsLookup   Thanks.
