The page was not displayed because the request entity is too large asp.net error

InfoPath alternatives for form designing SharePoint
Sometimes you will get this error in IIS 7.5 and windows server 2008 R2. The error message is “The page was not displayed because the request entity is too large“.
Sometimes also you will get the script error like below:
Sys.WebForms.PageRequestManagerServerErrorException: An uknown error occurred while processing the request on the server.  The status code returned from the server was: 413
The error may come:
– When you upload large file form your web page
– When you submitt web page of large content
To resolve this we have to increase uploadReadAheadSize in applicationHost.config file on IIS7.5.
For this:
Locate appcmd.exe in \windows\system32\inetsrv folder and run following command on command line tool
 appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 1048576 /commit:apphost
You can also manually increase by opening the IIS.
