Amazon S3 Library for REST in C#
Posted: Aug 14, 2008 12:38 PM PDT

I've setup the code in .Net and set the Access and Secret Key and get the following 'Protocol Error' error ...

ProtocolError

   at com.amazon.s3.AWSAuthConnection.makeRequest(String method, String bucket,
String key, SortedList query, SortedList headers, S3Object obj) in C:\Documents
and Settings\Administrator\Desktop\s3-example-cs-library\s3-example-libraries\cs
\AWSAuthConnection.cs:line 359
   at com.amazon.s3.AWSAuthConnection.checkBucketExists(String bucket) in C:\Doc
uments and Settings\Administrator\Desktop\s3-example-cs-library\s3-example-libra
ries\cs\AWSAuthConnection.cs:line 129
   at S3Sample.S3Driver.Main(String[] args) in C:\Documents and Settings\Adminis
trator\Desktop\s3-example-cs-library\s3-example-libraries\cs\S3Driver.cs:line 53

I'm running VS 2005 on .Net2 Framework on OSX via a Parellels Virtual machine, not that should make a difference.

Any help greatly appreciated.

Thanks

Richard.

Works great, but Response doesn't implement IDisposable, Jul 5, 2007 2:48 PM
Reviewer: "erik_cassel"

Be very careful when using this library. If you try to perform a LOT of operations you will quickly run out of Http connections. Here's my solution: 1) com.amazon.s3.Response must implement IDisposable in order to Close the WebResponse on Dispose. 2) Client code must wrap all calls that return a Response with a "using" clause.

Don't see performance boost on EU location, Jan 5, 2008 8:25 AM
Reviewer: appelappel

I tried upload of a 450k file to US and one to EU (US with a previous version built on an old version of this code) and I don't see a performance boost. Googled a bit and DNS has something to do with it at creation time of a bucket... Geert.
