Title: SparqlRemoteUpdateEndpoint fails with Invalid URI: The Uri string is too long.
Project: Core Library (dotNetRDF.dll)
Created By: http://koos-strydom.myopenid.com/
Milestone: none
Category: Core API
Priority: High
Type: Bug
Description: 

 HI, 

 The error occurs when a sparql update is submitted to any SparqlRemoteUpdateEndpoint when more than 250 triples is in the update query 

 here is a code snippet 

 var endpoints = http://192.168.1.10:8000/; 

 _endpointQuery = new SparqlRemoteEndpoint(new Uri(endpoints + sparql/)); 

 _endpointQuery.Credentials = GetCredentials(); 

 _endpointQuery.Timeout = 90000; 

 var endpointUpdate = new SparqlRemoteUpdateEndpoint(new Uri(endpoints + update/)); 

 endpointUpdate.Credentials = GetCredentials(); 

 ...... 

 ...... 

 StringBuilder sb = new StringBuilder(); 

 foreach (var pre in _workGraph.NamespaceMap.Prefixes) 

 { 

  sb.AppendLine(string.Format(PREFIX {0}: <{1}>, pre, _workGraph.NamespaceMap.GetNamespaceUri(pre))); 

 } 

 sb.AppendLine(string.Format(INSERT DATA {{ GRAPH <{0}>, scope.NamespaceURI)); 

 sb.AppendLine({ 

 foreach (var t in _workGraph.Triples) 

 { 

  sb.AppendLine(t.ToString(true)); 

 } 

 sb.AppendLine(} 

 sb.AppendLine(} 

 SparqlUpdateParser parser = new SparqlUpdateParser(); 

 SparqlUpdateCommandSet cmds = parser.ParseFromString(sb.ToString()); 

 endpoint.Update(cmds[0].ToString()); 

 ........ 

 and the stack trace
