Interesante
nunca se me hubiera ocurrido mandar dos parámetros con el mismo nombre pero diferente método.
Es más, nunca se me hubiera ocurrido investigar la prioridad de las variables de default:
Cita: All variables can be accessed directly by calling Request(variable) without a collection name. In this case, the Web server searches the collections in the following order:
*QueryString
*Form
*Cookies
*ServerVariables
If the same variable exists in more than one collection, the first one encountered will be used. It is strongly recommended that you use the collection name. For example, instead of Request.(AUTH_USER), use Request.ServerVariables(AUTH_USER).
