The answer to How to configure the web.config to allow requests of any length works fine.
Is there a way to change the limit for a specific service?
For example something like
<system.webServer>
<security>
<requestFiltering serviceName="MyService.asmx">//Only for 1 service
<requestLimits maxQueryString="32768"/>
</requestFiltering>
</security>
</system.webServer>
Adding a location element and setting the settings there seemed to do the trick
<location path="MyService.asmx">
<system.webServer>
<security>
<requestFiltering >
<requestLimits maxAllowedContentLength="102400000"/>
</requestFiltering>
</security>
</system.webServer>
If there is another/better solution feel free to post it
I have a asp.net web form app, i'm trying to upload a large file (13 mb) in a web form with a FileUpload control, when i press the submit button the web browser starts to upload the file. But, when the web browser finish the upload the app crash without reason, and doesn't lauch any exception, and not enter to the click event code (c#) of the submit button. In my web.config i have set the maxAllowedContentLength option and the maxRequestLength option.
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="52428800" />
</requestFiltering>
</security>
<httpRuntime targetFramework="4.5" executionTimeout="900" maxRequestLength="2097151" />
This is only happening in the web server(Windows Server 2012), in my local server this is not happening. In the webserver show a default error (I don't manage the server, so i can't see what custom error is happening)
i don't know why this is happening, because in the web server are apps with file upload options even more bigger.
Thanks for your help.
Modify your web.config by following Stricture, Here I'm using max File request length 13 MB & max Allowed Content Length 1 GB.
Now change Behind the <system.web> in web.config
<httpRuntime targetFramework="4.5" maxRequestLength="13631488" executionTimeout="9000" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="1000" />
And Behind the <system.webServer> in web config write this Code
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1073741824" />
</requestFiltering>
</security>
Thanks
the problem was a restriction on the server by the admin that doesn't allow upload large files. All the configuration given in this thread are correct.
It looks like you're missing the opening "security" tag in your web.config
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="52428800" />
</requestFiltering>
</security>
</system.webServer>
If your maxAllowedContentLength has a big value, your executionTimeout must be big, too!
It work in local because you don't need a long time to copy file in your hard.
But when you upload your site in server, you need more executionTimeout.
I have deployed my Website on Windows Server 2007. in IIS
I have added asp:FileUpload control
i have set <httpRuntime maxRequestLength="60000"/> under the <system.web> in my Web.Config file
but website doesn't allowed to Save the the file of maxlength as specified in web.config file.
how can i do this?
Thanks..
I think you need to use the following in the web.config file.
<configuration>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="60000" />
</requestFiltering>
</security>
</system.webServer>
</configuration>
In addition to #Maarten answer which is right.
The problem is IIS 7 or greater have default allowed value of maxAllowedContentLength is 30000000 Byte, So if you try to upload a file greater then this limits it will display Request filtering module is configured to deny a request that exceeds the request content length Issue error.
For a demo of this error which this link
i am trying to upload a file with filesize 80M bytes. on my pc ( cassini server) i can upload the file. On the webserver (iis 6) it throws an error?:
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
this is what i have in my web.config:
<system.web><httpRuntime maxRequestLength="716800"/></system.web>
Try below configuration setting:
<system.webServer>
<security>
<requestFiltering>
<!-- 50 * 1024 * 1024 = 52428800 -->
<requestLimits maxAllowedContentLength="52428800"/>
</requestFiltering>
</security>
</system.webServer>
I have a form that excepts a file upload in ASP.NET. I need to increase the max upload size to above the 4 MB default.
I have found in certain places referencing the below code at msdn.
[ConfigurationPropertyAttribute("maxRequestLength", DefaultValue = )]
None of the references actually describe how to use it, and I have tried several things with no success. I only want to modify this attribute for certain pages that are asking for file upload.
Is this the correct route to take? And how do I use this?
This setting goes in your web.config file. It affects the entire application, though... I don't think you can set it per page.
<configuration>
<system.web>
<httpRuntime maxRequestLength="xxx" />
</system.web>
</configuration>
"xxx" is in KB. The default is 4096 (= 4 MB).
For IIS 7+, as well as adding the httpRuntime maxRequestLength setting you also need to add:
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="52428800" /> <!--50MB-->
</requestFiltering>
</security>
</system.webServer>
Or in IIS (7):
Select the website you want enable to accept large file uploads.
In the main window double click 'Request filtering'
Select "Edit Feature Settings"
Modify the "Maximum allowed content length (bytes)"
To increase uploading file's size limit we have two ways
1.
IIS6 or lower
By default, in ASP.Net the maximum size of a file to be uploaded to the server is
around 4MB. This value can be increased by modifying the
maxRequestLength attribute in web.config.
Remember : maxRequestLenght is in KB
Example: if you want to restrict uploads to 15MB, set maxRequestLength to “15360” (15 x 1024).
<system.web>
<!-- maxRequestLength for asp.net, in KB -->
<httpRuntime maxRequestLength="15360" ></httpRuntime>
</system.web>
2.
IIS7 or higher
A slight different way used here to upload files.IIS7 has
introduced request filtering module.Which executed before
ASP.Net.Means the way pipeline works is that the IIS
value(maxAllowedContentLength) checked first then ASP.NET
value(maxRequestLength) is checked.The maxAllowedContentLength
attribute defaults to 28.61 MB.This value can be increased by
modifying both attribute in same web.config.
Remember : maxAllowedContentLength is in bytes
Example : if you want to restrict uploads to 15MB, set maxRequestLength to “15360” and maxAllowedContentLength to "15728640" (15 x 1024 x 1024).
<system.web>
<!-- maxRequestLength for asp.net, in KB -->
<httpRuntime maxRequestLength="15360" ></httpRuntime>
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!-- maxAllowedContentLength, for IIS, in bytes -->
<requestLimits maxAllowedContentLength="15728640" ></requestLimits>
</requestFiltering>
</security>
</system.webServer>
MSDN Reference link : https://msdn.microsoft.com/en-us/library/e1f13641(VS.80).aspx
for a 2 GB max limit, on your application web.config:
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" maxRequestLength="2147483647" executionTimeout="1600" requestLengthDiskThreshold="2147483647" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
</security>
</system.webServer>
I believe this line in the Web.config will set the max upload size:
<system.web>
<httpRuntime maxRequestLength="600000"/>
</system.web>
If its windows 2003 / IIS 6.0 then check out AspMaxRequestEntityAllowed = "204800" in the file metabase.xml located in folder C:\windows\system32\inetsrv\
The default value of "204800" (~205Kb) is in my opinion too low for most users. Just change the value to what you think should be max.
If you cant save the file after editing it you have to either stop the ISS-server or enable the server to allow editing of the file:
(source: itmaskinen.se)
Edit: I did not read the question correct (how to set the maxrequest in webconfig). But this informatin may be of interrest for other people, many people who move their sites from win2000-server to win2003 and had a working upload-function and suddenly got the Request.BinaryRead Failed error will have use of it. So I leave the answer here.
I've the same problem in a win 2008 IIS server, I've solved the problem adding this configuration in the web.config:
<system.web>
<httpRuntime executionTimeout="3600" maxRequestLength="102400"
appRequestQueueLimit="100" requestValidationMode="2.0"
requestLengthDiskThreshold="10024000"/>
</system.web>
The requestLengthDiskThreshold by default is 80000 bytes so it's too small for my application. requestLengthDiskThreshold is measured in bytes and maxRequestLength is expressed in Kbytes.
The problem is present if the application is using a System.Web.UI.HtmlControls.HtmlInputFile server component. Increasing the requestLengthDiskThreshold is necessary to solve it.
Max file size can be restricted to a single MVC Controller or even to an Action.
web.config <location> tag can be used for this:
<location path="YourAreaName/YourControllerName>/YourActionName>">
<system.web>
<!-- 15MB maxRequestLength for asp.net, in KB 15360 -->
<httpRuntime maxRequestLength="15360" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!-- 15MB maxAllowedContentLength, for IIS, in bytes 15728640 -->
<requestLimits maxAllowedContentLength="15728640" />
</requestFiltering>
</security>
</system.webServer>
</location>
Or you can add these entries in area's own web.config.
I know it is an old question.
So this is what you have to do:
In you web.config file, add this in <system.web>:
<!-- 3GB Files / in kilobyte (3072*1024) -->
<httpRuntime targetFramework="4.5" maxRequestLength="3145728"/>
and this under <system.webServer>:
<security>
<requestFiltering>
<!-- 3GB Files / in byte (3072*1024*1024) -->
<requestLimits maxAllowedContentLength="3221225472" />
</requestFiltering>
</security>
You see in the comment how this works. In one you need to have the sie in bytes and in the other one in kilobytes. Hope that helps.
If you are using Framework 4.6
<httpRuntime targetFramework="4.6.1" requestValidationMode="2.0" maxRequestLength="10485760" />
You can write that block of code in your application web.config file.
<httpRuntime maxRequestLength="2048576000" />
<sessionState timeout="3600" />
By writing that code you can upload a larger file than now
If you use sharepoint you should configure max size with Administrative Tools too:

I have a blog post on how to increase the file size for asp upload control.
From the post:
By default, the FileUpload control allows a maximum of 4MB file to be uploaded and the execution
timeout is 110 seconds. These properties can be changed from within the web.config file’s httpRuntime section. The maxRequestLength property determines the maximum file size that can be uploaded. The
executionTimeout property determines the maximum time for execution.
If it works in your local machine and does not work after deployment in IIS (i used Windows Server 2008 R2) i have a solution.
Open IIS (inetmgr)
Go to your website
At right hand side go to Content (Request Filtering)
Go to Edit Feature Settings
Change maximum content size as (Bytes you required)
This will work.
