 Mostrar diálogo "Guardar como..." para cualquier archivo, Parte I
Pregunta: ¿Cómo hago en ASP para descargar cualquier archivo mostrando la ventana de diálogo "guardar como"?
A veces sucede en archivos como .txt, .jpg, .gif, etc que se abren directamente en el explorador, pues este script los descarga sin que se abra en el explorer del usuario. Solución:
Archivos principales almacenados en la carpeta "descargar" ssort.asp
