Autocompleteextender - HTTP 403.9 - Access Forbidden: Too many users are connected Internet Information Services

I have two textbox in a page each uses ASP.Net Ajax Autocompleteextender control.

asp:TextBox ID="txtLastName" runat="server" CssClass="PlainText" MaxLength="50"

Ajax:autocompleteextender id="aceLastName" runat="server" targetcontrolid="txtLastName" servicepath="~/AjaxService/Predictive.svc" servicemethod="GetLastName" minimumprefixlength="1" completioninterval="100" completionsetcount="8" EnableCaching="False"

asp:TextBox ID="txtFirstName" runat="server" CssClass="PlainText" MaxLength="50" Ajax:autocompleteextender id="aceFirstName" runat="server" targetcontrolid="txtFirstName" servicepath="~/AjaxService/Predictive.svc" servicemethod="GetFirstName" minimumprefixlength="1" completioninterval="100" completionsetcount="8" EnableCaching="False"

However after typing certain characters all of a sudden Autocompleteextender stops working. Upon refresing the page i get HTTP 403.9 - Access Forbidden: Too many users are connected Internet Information Services

Solution

  • Found that I was not closing connection to webservice, so with each key press it was opening a new connection.
