httpwebrequest - ETag not being returned by WebResponse Header in c# -

i trying extract etag response header. exist in response. can see using firebug , can see in response object using inspector:

status: 200 ok x-api-version: 1.3.2 access-control-allow-origin: * x-runtime: 0.151298 connection: keep-alive content-length: 8185 cache-control: public, max-age=11216 content-type: application/json; charset=utf-8 date: fri, 09 mar 2012 01:40:05 gmt expires: fri, 09 mar 2012 04:47:01 gmt etag: "bd3fe1123a8f55e01ca859f4804e8fbe" last-modified: fri, 09 mar 2012 00:47:01 gmt server: nginx/1.0.11 

all other code working fine, making httpwebrequest, getting respose etc. problem null when trying etag (which existing in response header).

here simplified code:

        var request = (httpwebrequest)webrequest.create(validuri);         setheaders(); // helper function set basic headers.         var response = request.getresponse();          var stream = response.getresponsestream();         var reader = new streamreader(stream);         var result = reader.readtoend();          var etag = response.headers.get("etag"); 

anyone know why can't seem extract existing etag?

your code not reproduce problem describing. problem in have not mentioned. here short complete program based on code, executes , print out value of etag without problem:

using system; using system.io; using system.net;  namespace so9628006 {     class program     {         static void main()         {             var request = (httpwebrequest)webrequest.create("http://www.fiddler2.com/fiddler/fiddler.css");             var response = request.getresponse();              var stream = response.getresponsestream();             var reader = new streamreader(stream);             var result = reader.readtoend();              var etag = response.headers.get("etag");              console.writeline(etag);          }     } } 

output:

"6c3673ba919ec71:243"
