OpenLayer加载WFS图层及C#编写ASP.net代理解决跨域问题

OpenLayer跨域访问geoserver居然要用到代理，貌似Felx就不用。Java实现OpenLayers跨域代理程序 http://www.linuxidc.com/Linux/2014-01/95411.htm用C#编写代理网上普遍是这样的： public class GeoServerProxy1 : IHttpHandler
{ public void ProcessRequest（HttpContext context）
{
if （context.Request.QueryString["URL"] ！= null）
{
string url = "";
url = context.Request.QueryString["URL"].ToString（）;
HttpWebRequest loHttp = （HttpWebRequest）WebRequest.Create（url）;
loHttp.Timeout = 10000; // 10 secs
loHttp.UserAgent = "Web Client";
HttpWebResponse loWebResponse = （HttpWebResponse）loHttp.GetResponse（）;
Encoding enc = Encoding.GetEncoding（65001）;
StreamReader loResponseStream = new StreamReader（loWebResponse.GetResponseStream（）, enc）;
string lcHtml = loResponseStream.ReadToEnd（）;
context.Response.Write（lcHtml）;
loWebResponse.Close（）;
loResponseStream.Close（）;
}
} public bool IsReusable
{
get
{
return false;
}
}
}但是上面这种情况，没有考虑post，不适用于openlayers官方的wfs协议访问，但是可以用于http查询方式的访问，例如：JS代码：vectorLayer = new OpenLayers.Layer.Vector（"覆冰点", {
protocol: new OpenLayers.Protocol.HTTP（{
//url: "http://10.180.80.206:9000/geoserver/sdgis/ows？service=WFS&version=1.0.0&request=GetFeature&typeName=sdgis:V_YL_24&maxFeatures=50",
//url: "http://10.180.80.206:9000/geoserver/sdgis/ows？service=WFS&version=1.0.0&request=GetFeature&typeName=sdgis:GIS_WEATHER_FORECAST&maxFeatures=50",
url: "http://10.180.80.206:9000/geoserver/sdgis/ows？service=WFS&version=1.0.0&request=GetFeature&typeName=sdgis:V_FBJC_PT&maxFeatures=50",
format: new OpenLayers.Format.GML（）
}）,

}）,

}）;
