Upload large file to Blob Storage getting corrupted?
Application Type
Traditional Web
Platform Version
11.12.1 (Build 30407)


I was trying to upload large file to Azure Blob Storage by calling REST API.  I have also modified the server setting based on the post here https://www.outsystems.com/forums/discussion/20948/problems-uploading-large-approx-200mb-osp/.

For file smaller then 100MB, it works just fine.  But if I uploaded something bigger than 200MB and downloaded it back to my PC, it got corrupted.  The REST API does work in Postman (tried 6GB with no problem) so I guess there is something wrong with the server setup.  The problem is I have no idea where to look at.

I have also used some binary file comparer software to compare the original file and the downloaded file. Found out beside the size and some bytes, they are quite different!

Any suggestion would be greatly appreciated.



Hi William,

Yes , I think you need to do some configurations changes iis server to allow max content length
