Dynamsoft TWAIN Products

Hi,

We use Dynamic Web Twain ActiveX component to upload scanned documents. The problem is with SSL connections. In code, we specified as IsSSL=true and secure port as 443 (which is correct) but it does not work. Here is the code fragment:

HostAddress = "myapp.test.com";
frmScan.DynamicWebTwain1.HTTPPort = "443";
frmScan.DynamicWebTwain1.IsSSL = true;
result = frmScan.DynamicWebTwain1.HTTPUploadThroughPost(HostAddress, 0, "/MyActionPage.aspx", "MyScannedFile.jpg");

"result" is false and ErrorString tells something like "http://myapp.test.com:443/MyActionPage.aspx cannot be accessed" (the message indicates that the protocol is HTTP but not HTTPS. When I copy & paste this address to address bar of a browser, I get same error. But when I replaced the "http://" part with "https://" everything works fine)

When I check the requests made by the browser using Fiddler Proxy Debugger program, I see that Dynamic Web Twain component trying to use "HTTP" protocol and 443 port number attached to host address to upload file:

Protocol: HTTP
Host: myapp.test.com:443

Everything seems fine with the post operation except protocol. How can I switch the protocol to HTTPS? Is there anything we should do other than setting IsSSL=true and HTTPPort="443" ?
