Is there a default http body size limit set by iis8, and if so, what is it?

  • 772

Is there a limit, and if so what is it? The following page:

http://www.iis.net/configreference/system.webserver/asp/limits

explains the following:

the maxRequestEntityAllowed attribute specifies the maximum number of bytes allowed in the entity body of an ASP request. If a Content-Length header is present and specifies an amount of data greater than the value of maxRequestEntityAllowed, IIS returns an HTTP 403 error response.

I'm not sure where I would find this attribute or if there's a standard default value I can usually expect.

iis-8

  1. Just to make sure, the configuration attribute you describe is not a general IIS setting. It is for classic ASP only and affects the size of the request body, or the amount of data you can send in a POST when submitting a form.

    It has nothing to do with the size of the body in an html page.

    The default setting for this is 200000 bytes as you can see in the UI under 

    ASP - Limit Properties - Maximum Requesting Entity Body Limit

    When using IIS PowerShell cmdlets you can use:

    Get-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -location 'Default Web Site' -filter "system.webServer/asp/limits" -name "maxRequestEntityAllowed"

    to find that value.
