PSEXEC for loading a webpage on a remote server

In the article named PowerShell Snap-in: Creating Web-Sites, Web applications, Virtual Directories and Application Pools, there is an explanation of how you can download the contents of a specific webpage from powershell to make sure that a deployment was successful and that the apppool and site load into memory following their creation.  The code for that looks like:

$webclient =New-ObjectNet.WebClient

$webclient.DownloadString("http://localhost:8080/");

How could I do this using PSEXEC?
