how to check current value of UploadReadAheadSize

Question

Is there any way I can find out what's the current value or file size limit of UploadReadAheadSize for IIS on windows server 2003.

Answer 1

adsutil get w3svc/UploadReadAheadSize

Above command worked for me and thats what I was looking for.

Answer 2

you cant access it as there is no interface to get the value, the default value is 48kb I belive.

if its related to you uploading a file, the default size limmit is set to 50mb by default.

These settings (default settings) have been inplace for DOS attack i think hence why they are small in size! There are a couple of ways you can change it if a third party needs to use it that you need it to....

for this you need to change the metabase to a higher values like so:

you need to use Adsutil with the following script:

Adsutil set w3svc/uploadreadaheadsize "100000000"

it sets it to 100mb

or

open cmd

add this command cd.. untill you get to the root c://

add this cd c:\Windows\systems32\inetsrv

then add the following command:

appcmd set config "My Site/MyApp" -section:requestFiltering -requestLimits.maxAllowedContentLength:104857600 -commitpath:apphost

or add the following to app.config

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="65535" />
      </requestFiltering>
    </security>
  </system.webServer>

Or you can use this third party app to see the values ;)
