I changed the maxAllowedContentLength to
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="5024000000" />
</requestFiltering>
</security>
In my web.config, but when running on IIS7 I get this error:
The 'maxAllowedContentLength' attribute is invalid. Not a valid unsigned integer
but when I run in the VS server it run normally without any errors.
How to config my website to allow upload files with 500MB size, without this problem on IIS7?
This question is related to
asp.net
iis-7
file-upload
.net-4.0
IIS v10 (but this should be the same also for IIS 7.x)
Quick addition for people which are looking for respective max values
Max for maxAllowedContentLength
is: UInt32.MaxValue
4294967295 bytes
: ~4GB
Max for maxRequestLength
is: Int32.MaxValue
2147483647 bytes
: ~2GB
web.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<!-- ~ 2GB -->
<httpRuntime maxRequestLength="2147483647" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!-- ~ 4GB -->
<requestLimits maxAllowedContentLength="4294967295" />
</requestFiltering>
</security>
</system.webServer>
</configuration>
The limit of requests in .Net can be configured from two properties together:
Web.Config/system.web/httpRuntime/maxRequestLength
Web.Config/system.webServer/security/requestFiltering/requestLimits/maxAllowedContentLength
(in bytes)References:
Example:
<location path="upl">
<system.web>
<!--The default size is 4096 kilobytes (4 MB). MaxValue is 2147483647 KB (2 TB)-->
<!-- 100 MB in kilobytes -->
<httpRuntime maxRequestLength="102400" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!--The default size is 30000000 bytes (28.6 MB). MaxValue is 4294967295 bytes (4 GB)-->
<!-- 100 MB in bytes -->
<requestLimits maxAllowedContentLength="104857600" />
</requestFiltering>
</security>
</system.webServer>
</location>
