如何更改IIS 7.0的maxAllowedContentLength？

Question

Ii have a problem similar to: How to set the maxAllowedContentLength to 500MB while running on IIS7?

The difference is that I have already modified my web.config to accept files upto 2 Gb in size but when try and upload a large file, I get the following error:

The request filtering module is configured to deny a request that exceeds the length of the content.

my web.config is this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime executionTimeout="999999" maxRequestLength="2097151"/>
        <customErrors mode="Off"/>      
        <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />
            <membership>
            <providers>
            <clear/>
            </providers>
        </membership>
        <profile>
            <providers>
            <clear/>

            </providers>
        </profile>
        <roleManager enabled="false">
            <providers>
            <clear/>

            </providers>
        </roleManager>
</system.web>
<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="2097151" />
        </requestFiltering>
    </security>
</system.webServer>

I still receive the error when i try to upload a file that it is only 131 MB .

So, what should I set in the maxAllowedContentLength settings to allow people to upload files over 100 MB please?

Answer 1

While MaxRequestLength is number of kilobytes , maxAllowedContentLength is number of bytes . Multiply it again by 1024, and it should work fine.

maxAllowedContentLength
Optional uint attribute.
Specifies the maximum length of content in a request, in bytes.
The default value is 30000000.

Type inetmgr in windows Run (WinKey + r) click your server name on left panel and in right panel in IIS section double click Request Filtering. on the rightest panel click Edit Feature Settings... . In Request Limits section you can change the maxAllowedContentLength .

If you want change maxAllowedContentLength just in one of your sites, on the left panel select your site under Sites and go the same way as above to change it.
