Android Question Multiple concurrent Http web service calls

[swabygw]

In my program, I make two (and, hopefully, more eventually) web service requests. If I call them sequentially, they work fine. I'd like to run them concurrently to speed up the request/response. But, if I call them concurrently, as in the code below, what happens is that the first one runs twice (the logs on my server confirm that).

Http.makeHttpRequest(Http.myXmlFunc1(UserID), "myJobName1", Me)
Http.makeHttpRequest(Http.myXmlFunc2(UserID), "myJobName2", Me)

Sub makeHttpRequest(xmlRequestString As String, jobName As String, targ As Object)
  Dim outXML As String = xmlRequestString
  Dim url As String = "http://www.mylink.com/mywebservices.asmx"
  Dim job1 As HttpJob
  job1.Initialize(jobName, targ)
  job1.PostString(url, outXML)
  job1.GetRequest.SetContentType("text/xml")
  job1.GetRequest.Timeout = 5000 
  Log("HTTP job started: " & jobName)
End Sub

- "Http" is my code module.

Does doing this concurrently properly require using the Threading library? (I'm trying to avoid this) If so, any chance there's an example of concurrent Http requests? (I'm still working on understanding the examples in the Threading library zip file)

FYI - still wondering if Threading is more efficient here, but I did find why the same request is firing twice: the second request was merely appending the XML to the XML in the first request...fixed this.

HttpUtils2 sends all the requests in the background. You don't need to do anything special to send concurrent requests.
