Related 3. I am able to upload 10 mb file also where as max is 30 mb as I declared. I think by increasing your executionTimeout to some more you should be able to upload.
Thanks for the help. But I have tried different values before and I still get timeout, where my browser says this page can not be found. The problem is that i have my max request length set to set to 2 GB and my timeout set 4 min and I am not able to upload 2MB and timeout often occurs between 30 and 45 seconds.
So, I am not clearing my own values set in teh webconfig file. Because of the differeing times I am tempted to concluded that the file size has something to do with my issue. I have set my max request size pretty high, that is why I was asking if there could be a limit somewhere else?
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. The error is: The value must be inside the range Source Error: [No relevant source lines] Source File: web.
One issue I have not mentioned, is that my application can work from some areas and not others depending on the ISP. I think this has to do with connection speeds but I amnot sure. For example people from Mexico have the same file upload problem I do, But people from Panama don't. The file is received from a multipart request and directly processed or saved by the app. Streaming doesn't improve performance significantly. Streaming reduces the demands for memory or disk space when uploading files.
Streaming large files is covered in the Upload large files with streaming section. Use a Fetch Polyfill for example, window. The sample app demonstrates multiple buffered file uploads for database and physical storage scenarios.
When displaying or logging, HTML encode the file name. An attacker can provide a malicious filename, including full paths or relative paths. Applications should:.
The examples provided thus far don't take into account security considerations. Additional information is provided by the following sections and the sample app :. When uploading files using model binding and IFormFile , the action method can accept:. Binding matches form files by name. Use Path. GetRandomFileName to generate a file name without a path. In the following example, the path is obtained from configuration:. The path passed to the FileStream must include the file name. If the file name isn't provided, an UnauthorizedAccessException is thrown at runtime.
Files uploaded using the IFormFile technique are buffered in memory or on disk on the server before processing. Inside the action method, the IFormFile contents are accessible as a Stream. In addition to the local file system, files can be saved to a network share or to a file storage service, such as Azure Blob storage. GetTempFileName throws an IOException if more than 65, files are created without deleting previous temporary files. The limit of 65, files is a per-server limit.
For more information on this limit on Windows OS, see the remarks in the following topics:. To store binary file data in a database using Entity Framework , define a Byte array property on the entity:.
Specify a page model property for the class that includes an IFormFile :. IFormFile can be used directly as an action method parameter or as a bound model property. The prior example uses a bound model property. Use caution when storing binary data in relational databases, as it can adversely impact performance. The examples provided don't take into account security considerations. The 3. The file's antiforgery token is generated using a custom filter attribute and passed to the client HTTP headers instead of in the request body.
Because the action method processes the uploaded data directly, form model binding is disabled by another custom filter. Within the action, the form's contents are read using a MultipartReader , which reads each individual MultipartSection , processing the file or storing the contents as appropriate.
After the multipart sections are read, the action performs its own model binding. The initial page response loads the form and saves an antiforgery token in a cookie via the GenerateAntiforgeryTokenCookieAttribute attribute. The attribute uses ASP. NET Core's built-in antiforgery support to set a cookie with a request token:. I'd file an issue in the aspnet repo, then, where the product team will see it, in addition to here you can reference this one. Good shout, thanks ardalis.
There was one limit that I don't think has been fully resolved, but I don't think it applies to your scenario "it's self-hosted - locally - and running as a docker container when it's live". I don't recall the details or workarounds for it Since we have an open PR with massive updates for this topic, I'm going to close this issue.
If you look at the content on the PR and have feedback, provide it on the PR. I'll take a look over there. At the very least, placing the feedback on the PR will surface it to engineering when they review the PR.
I don't have an ETA on that review tho Thanks for the update guardrex.
