Générer du trafic web aléatoire depuis Internet Explorer avec PowerShell

• Mise à jour le 07 févr. 2019

J'ai eu besoin de simuler du trafic web sur de nombreuses stations Windows. Ne pouvant me démultiplier j'ai écris un script PowerShell qui ouvre de façon aléatoire des sites web avec Internet Explorer ou télécharge des fichiers depuis internet.
