IIS7 to configure the maximum upload attachment size need to pay attention to the matters and Procedures _win Server

IIS6 default allowed maximum upload size of 4M, before IIS7, when we need to expand the upload limit, such as the need to upload the attachment limit to 50M, you can do the following configuration in Web.config:

Copy Code code as follows:

<system.web>
</system.web>

After using IIS7, in addition to the above configuration, you need to note
Select a virtual directory, select the function view----Double-click the request filter---Right click on the edit function test, which is the maximum allowable content length, the default is 30M

In other words, after using IIS7, if you want to upload the 50M attachment, you have to modify the above two places.
