Okay, I've figured it out. It seems I left out some information
from my original post that might of helped.
The problem was in my aspx code that generated the xml for the
HTTPService. I needed to make sure not to cache there. I'm showing
my whole aspx code for others in case they run up with this
problem. I love it when it takes two days to write four lines of
code.
Thanks Tracy for your original post, it got me thinking in the right
direction.
****************Code .net aspx****************
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
Dim strSQL As String
Dim strUser As String
Dim strWhere As String
Dim Conn As New SqlConnection
("Server=MyServer;Database=MyDB;UID=UserID;PWD=")
'+++here is where I stop the caching+++++++
Response.Buffer = True
Response.ExpiresAbsolute = DateAdd(DateInterval.Day, -1,
Today.Now)
Response.Expires = 0
Response.CacheControl = "no-cache"
'+++++++++End of new cache code+++++++
Response.ClearContent()
Response.ContentType = "text/xml"
If Not Request.QueryString("File") = "" Then
strWhere = "FileNameID = " & Request.QueryString("File")
End If
If Not Request.QueryString("Search") = "" Then
strWhere = "Tag Like '%" & Request.QueryString("Search")
& "%'"
End If
strSQL = "SELECT * FROM tblTableName WHERE " & strWhere
Conn.Open()
Dim myCmd2 As SqlCommand = New SqlCommand(strSQL, Conn)
Dim myReader2 As SqlDataReader = myCmd2.ExecuteReader()
Dim w As XmlTextWriter = New XmlTextWriter
(Response.OutputStream, Encoding.UTF8)
w.Formatting = Formatting.Indented
w.WriteStartDocument()
If Request.QueryString("File") Then
w.WriteStartElement("FileID")
w.WriteAttributeString("FileID", Request.QueryString
("File"))
While myReader2.Read
w.WriteStartElement("Tag")
w.WriteString(myReader2.Item("Tag"))
w.WriteEndElement()
End While
Else
w.WriteStartElement("Tag")
w.WriteAttributeString("Tag", Request.QueryString
("Search"))
While myReader2.Read
w.WriteStartElement("FileName")
w.WriteString(myReader2.Item("FileNameID"))
w.WriteEndElement()
End While
End If
w.WriteEndElement()
w.Close()
End Sub
****************end of code**********************
