Upload Large Files From Application?

Feb 15, 2010

I am building a website where i need a page where user can upload large video files, i have created WCF service with streaming but i am calling that WCF service from Button_Click event of web page.

I have used below mentioned article for WCF service creation

WCF Streaming

I have used streaming as it should be efficient and should not be buffered in memory of server.

Now questions

1) I am having doubts that the entire file is uploaded to the web server and then it is transferred to WCF Service server...if this is true then i am not getting advantage of streaming as well as iis and web server will be down very soon if user uploads large file or multiple user are uploading files con currently

2) Is there any other efficient way to do same operation with some other technique

EDIT :

If I am not calling WCF Service method from ASP .Net code in that case also it is transferring bytes to the web server which i have checked with HTTPFox

I have checked above thing with upload control and putting one button on UI whose click event is bound to one method in code behind.

So, still i am having that confusion that how data is transferred

Client Machine - Web Server (ASP .Net Application) - Service Server (WCF Service)
Client Machine - Service Server (WCF Service)

NOTE : If i am putting a debug point on button_click and uploading 10 kb file it hits that in less then 1 sec. but if i am uploading 50 mb file then it is taking time.

I placed code of calling WCF service inside that button_click event

Upload Large Files On Webpage?

Feb 11, 2011

We use the MojoPortal to a website and have some problems to upload files that is around 100 MB with the upload module. (Pleas note that this has probably nothing to do with MojoPortal but with the ASP.NET and the IIS)

The MojoPortal is set to use regular file Upload(not Neat Uploader) and to be able to upload big files we have set the following :

<httpRuntime maxRequestLength="2097151" executionTimeout="18000" requestValidationMode="2.0"/>

And :

<compilation debug="false" defaultLanguage="C#" targetFramework="4.0">

The problem is that the upload will cacel after a couple of minuts (Aborted).

Is there any other values that I need to set to make this possible? The MojoPortal itself should not have any settings for this as far as I know so its regular ASP.NET 4.0.

Anyone got some good pointers at an open source (article for creating your own would even be better) component to upload large files.SlickUpload for instance works great, and surely worth the money, but as this is for a pet project, a paid solution is just not what I'm after.

Iis7 - Preventing Upload Of Large Files?

Oct 25, 2010

We'd like to restrict the maximum upload file size in our web site. We've already set the appropriate limits in our web.config. The problem we're encountering is if a really large file (1 GB, for example) is uploaded, the entire file is uploaded before a server-side error is generated, and the type of the error is different whether the file is huge or not. Is there a way to detect the size of a pending file upload before the actual upload takes place?

Here's my relevant web.config settings that restrict requests to 16 MB:

[Code]....

Update:

I know that client-side technologies like Flash can detect file sizes before upload, but we need a server-side workaround because we're wanting to target platforms that have no Flash/Java/ActiveX/Silverlight support. I believe that IIS or ASP.NET has a bug that's allowing large files to be uploaded despite the limits, so I've filed a bug here.

Would an ISAPI extension give me more control over request processing than HTTP modules and handlers, such as allowing me to abort an upload if the Content-Length header is seen to be larger than the allowed limit?

Update 2:

Sigh. Microsoft has closed the bug I filed as a duplicate but has provided no additional information. Hopefully they didn't just drop the ball on this.

Solution For A BitTorrent Uploader / Able To Upload Extremely Large Files?

Jan 25, 2011

I have a requirement by my client to be able to upload extremely large files.

I'm talking about 7 GB files. The website they are currently running on is a ASP.NET 4.0 app, so obviously the standard upload scheme for my web app is not going to work.

I'm tossing around multiple options trying to figure out what the best route to go would be.

One option I'm thinking about seeing if I can do would be to have a BitTorrent Uploader. The end users for this app will typically have the same file on hand, so the idea would be that an end user would go to the site, say that they wanted to upload a file. At that point, they would pick the file, and then the server would immediately mark that person as a seed for that file. Then, my web app would go to a preconfigured leech on our side, and instruct the leech to download the file. I would expect at some point during or after this process the torrent would do some magic to find other seeders on the client's network, or wherever, but that's the idea.

Is there any technology out there already that does this? Or am I describing something that I'm going to have to build from the ground up?

How To Upload More Than One Large Images At Same Time

Jun 28, 2010

internet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.

The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.

Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.
