HttpWebResponse Problems

Sean Chapman

ok, heres the problem.. i have an asp.net page that im using to kind of
relay information back and forth. So on the Page_Load i make a request to a
webservice and return some xml back to the first calling app. now... i wrote
a test app to try it out, but i cannot get the proper data from it. It
always says the the ContentLength is -1 so my my StreamReader.Re adToEnd
throws an exception.. heres the chunk of code in the driver app:

webRequest = (HttpWebRequest )WebRequest.Cre ate(webRequestS erver);

webRequest.Meth od = "POST";

webRequest.Cont entLength = doc.InnerXml.Le ngth;

webRequest.Cont entType = "text/xml";

webRequest.Keep Alive = false;

myWriter = new StreamWriter(we bRequest.GetReq uestStream());

myWriter.Write( doc.InnerXml.To String());

myWriter.Close( );

webResponse = (HttpWebRespons e)webRequest.Ge tResponse();
StreamReader myReader = new StreamReader(we bResponse.GetRe sponseStream()) ;
responseFromSer ver = myReader.ReadTo End();

myReader.Close( );

Im thinking the problem is on the asp page. A weird thing i came across is
that it wont let me do a XmlDoc.Save on the response. so what i end up doing
is this:

myXMLDoc.LoadXm l("xmlString" )

responseXML = myXMLDoc.Docume ntElement

Response.Clear( )

Response.Buffer Output = True

Response.Conten tType = "text/xml"

responseXML.Wri teTo(New XmlTextWriter(R esponse.Output) )

Response.Flush( )

Response.Close( )

I tried adding and appending a ContentLength Header to the response, but no
good.. and you can set the content-type fine. but there is no property for
Content-Length.

so what do i do

thanx for any help

Try "Response.E nd" at the very bottom of your code.

Time Out for Binaryreader from HTTPWebResponse

by: Denny Rue | last post by:

Iâ€™ve created VB code to download files from a web site through the use of HTTPWebRequest, HTTPWebResponse and BinaryReader. The HTTPWebRequest has a TimeOut property to limit how long it waits for a corresponding HTTPWebResponse. This works just fine. However, the timeout does not appear to apply to a BinaryReader created from the HTTPWebResponse. Iâ€™ve had instances where the procedures will hang indefinitely during the download. ...

Empty HttpWebResponse length for some url (with queries?)

by: Jason Manfield | last post by:

For some URLs (e.g.http://v3.espacenet.com/origdoc?DB=EPODOC&IDX=WO2005028634&F=0&QPN=WO2005028634), the content length for the HttpWebResponse I get with request.GetResponse in empty. The response.GetResponseStream() also empty. However, I am able to open the URL in the browser (the URL address remains the same; it is not redirected) Here is the code snippet: HttpWebRequest req = (HttpWebRequest)WebRequest.Create(pageAddress);

HttpWebResponse.CharacterSet

by: Jason Manfield | last post by:

Why does HttpWebResponse.CharacterSet always return ISO-8859-1? I am accessing a Chinese Web site (http://cn.yahoo.com) -- View Source in IE shows the character set to be "gb2312", but the HttpWebResponse shows it to be ISO-8859-1. Websites like www.cnn.com also show the character set to ISO-8859-1 Here is the code snippet: string pageAddress = "http://cn.yahoo.com"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(pageAddress);

Can't get HttpWebResponse to work - timeout or connection closed

by: Noggin The Nog | last post by:

Hi all, I've been trying to get HttpWebResponse to work, but whenever I try I get "The operation has timed-out".

HTTPWebResponse Timeout problems

by: Brent | last post by:

I thought I was doing a simple thing, here -- asking a server for a text document, getting the first 150 lines, and then returning the lines. But I keep getting timeout errors: "Exception Details: System.Net.WebException: The operation has timed-out." I read somewhere that generally these errors come from not closing a HTTPWebResponse connection before opening another. But -- to my knowledge -- I've shut down connections in every way I...

HttpWebResponse how does it end

by: Nuno Magalhaes | last post by:

In pages that there is no content length, how does HttpWebResponse knows where the page ends? And what kind of objects/methods does it retrieve? Does it only retrieve the initial page without any images, i.e., does it only makes one "GET / HTTP/1.1\r\n\r\n"? Because I'm doing some projects on a webclient (to measure some statistic times) and the total bytes get byte HttpWebResponse are lower than the total objects I get via socket way. ...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
