Web Service Time Out Problem After Two Calls

[ImranArshad]

Hi,

I am calling a web service in my ASP.NET (2.0) application. Web Service return a audio recording URL which i pass to Window Media player object .

it works fine for first two call but for third call it throws exception

"System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> The operation has timed out".

bellow is the code

//Create a calss which is inherited by the web service proxy calss

public class ProxyChild : WebServiceProxy

{

public ProxyChild()

{}protected override WebRequest GetWebRequest(Uri uri) 
{

HttpWebRequest webRequest = (HttpWebRequest)base.GetWebRequest(uri);

webRequest.KeepAlive = false; 
webRequest.ReadWriteTimeout = 600000;

webRequest.Timeout = 600000;

return webRequest; 
}

}

//Main Class which call web service method

public partial class AudioPlayer : System.Web.UI.Page 
{

protected void Page_Load(object sender, EventArgs e) 
{

GetWebUrl(); 
}

private void GetWebUrl() 
{

string WebAccessPath=null; 
StringBuilder sb = new StringBuilder();

CampaignManagement campaignManagment = new ProxyChild();

WebAccessPath = campaignManagment.GetUrl();

sb.Append("<OBJECT ID=\"MediaPlayer\" WIDTH=\"310\" HEIGHT=\"100\""); 
sb.Append("CLASSID=\"CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95\" STANDBY=\"Loading ");

sb.Append("Windows "); 
sb.Append("Media Player components...\" TYPE=\"application/x-oleobject\" VIEWASTEXT> ");

sb.Append("<PARAM NAME=\"FileName\" VALUE=\"" + WebAccessPath + "\"> "); 
sb.Append("<PARAM name=\"autostart\" VALUE=\"true\"> ");

sb.Append("<PARAM name=\"ShowControls\" VALUE=\"true\"> "); 
sb.Append("<param name=\"ShowStatusBar\" value=\"true\"> ");

sb.Append("<PARAM name=\"ShowDisplay\" VALUE=\"false\"> "); 
sb.Append("<EMBED TYPE=\"application/x-mplayer2\" NAME=\"MediaPlayer\"> ");

sb.Append("</EMBED> "); 
sb.Append("</OBJECT> ");

this.AudioPlayerdiv.InnerHtml = sb.ToString();// AudioPlayerdiv is the Name of server side div

} 
}

Is there any suggestion I am facing this problem from a week but did not find any solution

hi!
Have you been able to profile GetWebURL and find a line of code where it hangs? My suspicion would be some kind of threadlock over a resource in the constructor to ProxyChild, if the previous two instances are still waiting to be handled by garbage collection?
