Setting UrlSegmentMaxLength from commadline

Question

Is there a way to set the UrlSegmentMaxLength value for Http.sys using appcmd/netsh or any other commandline utility?

Answer 1

I change this for my deployment in powershell Set-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 500 Restart-Service W3SVC -Force

Answer 2

I realize this is an old question, but in case someone stumbles upon this, here's PowerShell one-liner that either creates the key and sets the value or updates existing value.

if ((Get-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -ErrorAction SilentlyContinue) -eq $null) { New-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 2048 -PropertyType DWord } else { Set-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 2048 }

As for restarting, I found that this works well (no need to restart the server):

Stop-Service http -Force
Start-Service http
Start-Service IISADMIN
Start-Service W3SVC
