I'm not certain how to configure ASP.NET to set the SECURE flag on all cookies, but I think you can add cookieRequireSSL=true or to your Web.config; that is important to do, and especially important if you have HTTP enabled or if you have some kind of redirect from HTTP pages to HTTPS pages.
Mexican flag is full of national symbolism. The green strip represents the Independence Movement. The white stripe represents the purity of the Catholic faith. The red stripe represents the Spaniards that joined in the quest for Independence and the blood of the national heroes. The emblem-shield symbolizes the Aztec heritage.
The modern Mexican flag celebrates a tradition of unity between Spanish immigrants and the approximately 700 indigenous Native American peoples who resided in Mexico at the time the Spanish Conquest began in 1517. The people of Mexico united to obtain freedom from colonial rule during the early 1800s.
