Solve IIS 8.5 Error message "The page was not displayed because the request entity is too large"

UploadReadAheadSize.txt

This is a quick overview about te IIS 8.5 error message "The page was not displayed because the request entity is too large", Our team 
was trying to publish a PHP app on IIS server, in this app our team was working on the improvement of app folder structure, after that 
when some clients was trying to work with it, the app had been throwing "The page was not displayed because the request entity is too
large" as response.

After an extensive search on the web we found a solution:

Command: appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 1048576 /commit:apphost

IIS Manager: <Server Instance> -> Management -> Configuration editor -> System.webServer -> serverRuntime -> UploadReadAheadSize, set 1048576

Restart server.
And take a rest...
