The Publishing Cache of SP2010 WebApplications

In a recent post I talked about the publishing cache. It turns out this also applies for Classic Authentication WebApplications. (from the original post:) Have a look into your Developer Dashboard to see what is going on; the warning and critical error are:

• 7362 - Warning Publishing Cache
• 7363 - Critical Publishing Cache

I have created a script to set the cacheSuperAccount and cacheReaderAccount on each webapplication in the farm. Be sure to create two seperate ___domain user accounts first. Then use this script from within you SP2010 PowerShell Prompt. It works on both Classic and Claims Based Authentication WebApps. Usage:

 .\script.ps1 -cacheSuperAccount "___domain\superuser" -cacheReaderAccount "___domain\superreader"

The updated PowerShell Script:

 param([string]$cacheSuperAccount= "sp2010\superuser",[string]$cacheReaderAccount= "sp2010\superreader")

write-host ""
write-host -f White "Configure the WebApp property: portalsuperuseraccount and portalsuperreaderaccount"

write-host ""
write-host -f Green "Stef van Hooijdonk - v1.0"

if (get-pssnapin $snapin -ea "silentlycontinue") {
    write-host -f Green "PSsnapin $snapin is loaded"
}
else {    
    if (get-pssnapin $snapin -registered -ea "silentlycontinue") {
        write-host -f Green "PSsnapin $snapin is registered"
        Add-PSSnapin $snapin
        write-host -f Green "PSsnapin $snapin is loaded"
    }
    else {
        write-host -f Red "PSSnapin $snapin not found" 
    }
}
