(Classic ASP) Asynchronous HTTP Upload
Demonstrates how to do an HTTP upload asynchronously in a background thread.
A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% set upload = Server.CreateObject("Chilkat_9_5_0.Upload") ' Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc) ' that will process the HTTP Upload. upload.Hostname = "www.mywebserver.com" upload.Path = "/receiveUpload.aspx" ' Add one or more files to be uploaded. upload.AddFileReference "file1","dude.gif" upload.AddFileReference "file2","pigs.xml" upload.AddFileReference "file3","sample.doc" ' Begin the HTTP upload in a background thread: success = upload.BeginUpload() If (success <> 1) Then Response.Write "<pre>" & Server.HTMLEncode( upload.LastErrorText) & "</pre>" Else Response.Write "<pre>" & Server.HTMLEncode( "Upload started...") & "</pre>" End If ' Wait for the upload to finish. ' Print the progress as we wait... Do While (upload.UploadInProgress = 1) ' We can abort the upload at any point by calling: ' upload.AbortUpload(); ' Display the percentage complete and the number of bytes uploaded so far..
