Limit Size of File Upload to a Web App
Uploading Large Files to IIS / NET. Core / ASP.NET
While the IT Striking WebDAV Server Engine can process files of any size (up to 8,589,934,592 Gb) the hosting environment or you WebDAV client may not back up large files upload.
Max Upload File Size in .Net Core
If you run your server on .NET Core, to set the maximum file upload size use theMaxRequestBodySize property. This holding exists for both Kestrel (KestrelServerLimits.MaxRequestBodySize) and for IIS (IISServerOptions.MaxRequestBodySize), you will set up this option depending on which web server you lot run your code. To completely remove the file upload limit fix this belongings to null:
services.Configure<IISServerOptions>(options => { options.MaxRequestBodySize = aught; }); services.Configure<KestrelServerOptions>(options => { options.Limits.MaxRequestBodySize = null; }); Removing the Request Filtering Module in IIS
If you run your server in IIS, in addition to setting theMaxRequestBodySize property, y'all must also remove the Request Filtering module. Even though this module provides configuration options, information technology can not process files over 2Gb max and volition intercept the request before .NET Cadre can process it. To remove the Request Filtering module:
- Unlock the RequestFilteringModule on the server level in IIS in Modules.
- Remove the RequestFilteringModule on the site level:
<system.webServer> <modules> <remove proper noun="RequestFilteringModule"/> </modules> </system.webServer>
Max Upload File Size in IIS and ASP.NET (.NET Framework)
If y'all host your WebDAV server in IIS and run your server on ASP.NET .Cyberspace Framework you must specify the file maximum upload size in web.config of your web application. By default maximum upload size is set to 4096 KB (4 MB) by ASP.NET. To increment the upload limit add an advisable section to your spider web.config file and specify the limit:
In the case of IIS 7.ten and later, both Integrated and Classic mode:

In the case of IIS 6.0:

The maximum file upload segment size for both ASP.Cyberspace 2.0 and ASP.NET four.0 is 2097151Kb = 2Gb. To upload files over 2Gb, you need to run your server on .NET Core or you demand the client application with resumable upload support.
Different with .NET Core, removing the Request Filtering module in example of .Net Framework project would not assistance to overcome the 2Gb limit, because the 2Gb limit too hardcoded in ASP.Internet (.Net Framework) code itself.
If yous need to upload files larger than 2Gb y'all must implement resumable upload interfaces and upload files with segments. Note that you volition need the WebDAV customer application that supports resumable upload, in this example, such equally Information technology Hit Ajax Browser or WebDAV Sample Browser. They automatically detect that your server is hosted in IIS, brake file into 2Gb segments and upload a file segment by segment.
Upload Content Buffering in ASP.NET two.0
The file upload is performed differently in ASP.NET 4.0-based application, HttpListener-based application and in ASP.Internet 2.0-based awarding. While ASP.NET four.0 and HttpListener passes file content directly to the engine, the ASP.NET 2.0 first saves file content in a temporary folder limiting upload capabilities and increasing server load. To avoid upload buffering in ASP.Net 2.0 on servers side, the Information technology Striking WebDAV Server Engine provides ITHitPutUploadProgressAndResumeModule that too significantly improves upload speed. To use the module in your web application add together it to modules section in web.config:
In the case of IIS 7.ten Integrated fashion:

In the case of IIS 7.x Classic mode and IIS 6.0:

If y'all enable this module in ASP.Internet 4.0 application it will be ignored.
Ever enable ITHitPutUploadProgressAndResumeModule in the following cases:
- If you are running your application in Visual Studio Development Server (not recommended).
- If yous are implementing resumable upload interfaces and hosting your server in ASP.Internet 2.0.
With ITHitPutUploadProgressAndResumeModule module you must e'er employ the DavContextBaseAsync(HttpContext) constructor.
Upload Timeout
To prevent canceling script execution when uploading a large file to the application hosted in IIS / ASP.Internet yous must increase script timeout value:

Note that if you shop your data in a database, often timeout may be caused by a database connection.
