Hi All,

We are using Amazon s3 as storage server to upload files from salesforce.It is working fine.

But some clients are facing issues with file upload/download due to their proxy restrictions.So the user who is uploading

the file is clueless about what went wrong.To handle this, I am trying to connect to https://s3.amazonaws.com

using XMLHttpRequest in Java script.If the request fails, I am displaying that "Unable to connect to

https://s3.amazonaws.com. Reason: Proxy Restriction".

XMLHttpRequest is failing because of cross domain problem.Can anyone guide me through this.Does anyone have

better approach?

Thanks

Gops
