Running a simple page that submits "POST" a username and password to the login.fcc.
The login.fcc page which has the "@smretries" Directive configured.
The SMTRYNO cookie is never created when the user fails to enter the right information.
How can be the SMTRYNO cookie generated?
The custom HTML Form was not POSTing the TYPE parameter to the FCC along with the User's Credentials.
The TYPE parameter contains the realm credentials bit mask returned by isProtected call.
When POSTing to the FCC with FCCCompatMode=Yes, the "TYPE=33554433" need to be added as a POST parameter to enable the Web Agent to generate the SMTRYNO cookie with the @smretries Directive Set.
Make sure the TYPE=33554433 is sent as POST parameter when the Web Agent ACO parameter FCCCompatMode is set to yes.
