No, this has nothing to do with beer -- but maybe it should?

httpRuntime and File Upload Limits

Still reeling from a flood of New Year work. Let me offer something brief. Rob Spitzer did a nice Win2K3 and IIS 6 presentation for WeProgram.Net last night. We were discussing some Win2K to Win2K3 migration issues, and besides this Response Buffer issue I discussed here, I mentioned some default settings regarding file upload size. Donny Mack wrote about using the httpRuntime element in web.config here, but in a nutshell let me share that web.config supports an <httpRuntime> element under the system.web section -- specifically something like this

will establish a max file upload size of 10,000 Kilobytes. You can set this more broadly in your machine.config, too.

Oh, yeah, Admin and Developer alike might find SAM's Windows Server 2003 Delta guide useful. Amazon it here. If my word isn't good enough, both Rob Spitzer (local Admin extraordinaire) and Darrell Norton (local Developer extraordinaire) highly recommend it too!

Happy .Netting

Still worth remembering that you're best to use ISAPI based file uploads even with ASP.NET. Issue is that for ASP.NET, the entire encoded file is stored in memory until the upload is complete - so if you're uploading a 10mb file, this will require at least 10mb of memory being used by the ASP.NET process. To get truly scalable uploads, ISAPI is the only real option...

Grant, to follow up on Scott's comment, you might want to take a look at Soft Artisans FileUp component to help manage both uploads and downloads from your web site.

I've also had good results from ABCUpload.NET - http://www.websupergoo.com/abcupload.net-1.htm
They are also offering a free license if you link back to their site (normally costs $249).

Thanks fellas, they advertise 4 GB upload which is WAY more than conventional asp.net file upload will handle. We might be buying a few licenses soon . . .
