Unable to open Excel documents in Office from SharePoint 2013

How I was able to get this working is the switch statement below. It may not be as surgical as other ways, but it was the only way I found to get this working. This switch statement allows the following programs through:

• Office 2010/2011/2013
• SharePoint Designer 2010/2013
• WebDAV/Open in Explorer (IE 9/10/11)
• Office Upload Center 2013
• SkyDrive/OneDrive 2013
• InfoPath 2013

switch -glob [string tolower [HTTP::header "User-Agent"]] {
    "*word*" -
    "*excel*" -
    "*office upload*" -
    "*office protocol discovery*" -
    "*soap toolkit*" -
    "*webdav-miniredir*" -
    "*frontpage*" -
    "*msfrontpage*" -
    "*shareplus*" {
        HTTP::disable
    }
    default {
        switch -glob [string tolower [HTTP::uri]] {
            "*owssvr.dll" {
                HTTP::disable
            }
        }
    }
}
