Así que sí, envié la mayor parte de la información necesaria para la respuesta posterior, pero la página de resultados no es la página siguiente, pero sigue siendo la misma página de destino.
Me estoy perdiendo algo aquí? No hay errores relacionados con la ejecución de mi código, solo el resultado no es el esperado. No faltan cookies ni nada por lo que no puede ser.
Respuesta aceptada
ctl00% 24plhBodyArea% 24btnAccept
no era el nombre correcto del campo ... en realidad era $ en lugar de que chrome cambió las salidas a% 24 por defecto, perdón por no darme cuenta ...
