vb.net - Setting Default Security Protocol -
i integrating on website authorize.net, using aim. have been testing on pc , far transactions went through , got response. however, when pushed changes online server, having issues. response string being returned empty. have checked admin interface , transactions occur when issue not listed.
update
it looks default securityprotocol using tls1.0/ssl3. once did servicepointmanager.securityprotocol = securityprotocoltype.tls12
. transaction received
is there way change default setting of servicepointmanager have value tls 1.2 not have set it?
if have program it, best set it? in application start in global asax, or each time request made?
