WCF / ASMX :: Missing XML Header And Envelope Header In SOAP Response With.Net (2.0) Web Service

Jul 19, 2010

In my ASP.Net (2.0) Web Service implementation (The implementation class derives from

System.Web.Services.WebService with WebServiceBinding confirming to WsiProfiles.BasicProfile1_1 .

The SOAP response sent out by the Service has two elements missing :

1> The XML header itself : (<?xml version="1.0">)

2> The opening and closing Envelope tags with NameSpace ("<S:Envelope xmlns:S=http://schemas.xmlsoap.org/soap/envelope/>" and "</S:Envelope>" ).

This results in "breaking" of my client unless the above mentioned headers are inserted at the client end, and my intent is to avoid bypasses at the client end as far as popssible.Is this the default behavior ?

WCF / ASMX :: Read And Modify Soap Message (Programmatically)?

Apr 1, 2011

I have a web service running somewhere... I have added a reference of the same in my project. I had used SOAP UI to check the outgoing and incoming SOAP messages.

Now what i need is to MODIFY the SOAP message after it has been created (I wont be creating the soap message manually,) modify as in, I mean to insert some element into the header (such as public key etc) and encrypt the contents present in the body.

I have tried a lot of googling and have come to conclusion that i may have to use the SoapExtension Class.But i just dont understand how to do it.

There are method like ProcessMessage(... which require SoapMessage as input parameter. Now how to read
a generated SoapMessage is still unclear to me. I dont want to read the Soap message using tools (fiddler, soapui etc). I wish to read it programmatically.

Listview - Reverting Response Header?

Jun 21, 2010

've programmatically created a listview, for displaying images. When you click on the download the ItemCommand is fired, and the browser sends the user the image as a binary response, using the following:

SPFile ImageIfile = spfolder.Files[ServerName];
byte[] bs = ImageIfile.OpenBinary();
string res = Page.Response.ContentType;
Page.Response.ContentType = "image/jpeg";
Page.Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(fileName))

This works, exactly once. Then neither the download link, nor the DataPage paging controls
work until you refresh (Indeed any postbacks).

EDIT: It's a SharePoint 2007 WebPart, this is the declaration of the ListView in the CreateChildControls method:

lv.ItemPlaceholderID = "itemPlaceholder";
lv.GroupPlaceholderID = "groupPlaceholder";
lv.ID = "MediaSearch";
lv.LayoutTemplate = new LayoutTemplate();
lv.GroupTemplate = new GroupTemplate();
lv.GroupItemCount = 4;
lv.ItemTemplate = new ItemTemplate();
lv.EmptyDataTemplate = this.Page.LoadTemplate("/usercontrols/MediaResults_Empty.ascx");

And this is the ItemTemplate and DataBinding

public class ItemTemplate : ITemplate
public void InstantiateIn(Control container)

List All Data Sources And Modify In Visual Studio 2008?

Jan 28, 2010

I've taken over an ASP.NET project and the previous dev used "dynamic" DSNs sprinkled throughout the application. These data sources are databound to several controls throughout the site.I'd prefer to use a system DSN that I would define on my dev machine and the production web server. This way if I need to change the location of the SQL database I can just change the system DSN on the server instead of modifying the code and recompiling the application in Visual Studio.What is the easiest way to list all these dynamic DSNs that are in use in this web site project in Visual Studio 2008 and modify them to use a system DSN instead?

C# - Modify Request.Headers["Referer"] When Performing Response.Redirect?

Aug 11, 2010

In the web app (C#, ASP.NET) I am working on at the moment, the value in Request.Headers["Referer"] can determine things like custom style. I have created a custom page with a drop down menu to test this functionality. So when the selected index changes, the value selected should be set in the Request.Headers["Referer"] then will be redirected (Response.Redirect), the receiving page will then pick up the value in Request.Headers["Referer"] and adjust the styling accordingly. However I haven't been able to set value for Request.Headers["Referer"]. Is it possible at all?

Website 1 sets the value in Request.Headers["Referer"], e.g. www.xyz.com and before doing Response.Redirect to www.website2.com

Website 2 picks up value in Request.Headers["Referer"], in this case www.xyz.com and do what it needs to do, i.e. styling etc.

WCF / ASMX :: Redirect Response In Web Service?

Aug 3, 2010

I read that webservices are basically used in backgroung. It can't be use for redirecting to some other url. Then what is meaning of following code which is from msdn. I am not able to implement this code.

Redirection If you need to provide a redirect response in your Web service, do not use the Context.Response.Redirect method because the HTTP response will differ from what the Basic Profile mandates. [R1130]

The following example shows how to give a redirect response that complies with the Basic Profile:

[WebMethod]public string HelloWorld(){ Context.Response.StatusCode = 307; Context.Response.AddHeader("Location","<redirect URL>"); return null;}

WCF / ASMX :: Speeding Up Response Time?

Jun 30, 2010

why classic asp pages run so much faster than consuming a web service in .net?

I have a classic asp page that consumes a web service like so:


I run a log of every transaction and the time from call of the page to finish is ALWAYS between 1 and 2 seconds.However, when I try to consume the web service through .net like so:


This way takes on average at LEAST 10 seconds. Sometimes less, but not often.

I guess I just assume it should be the other way around. How can i speed this up? Seriously, don't make me stick to classic asp pages!

C# - HTTP 502 Proxy Error - The Size Of The Response Header Is Too Large. Contact Your ISA Server Administrator. (12216)

Feb 23, 2011

Some of my users are getting the following error

HTTP 502 Proxy Error - The size of the response header is too large. Contact your ISA server administrator. (12216) Internet Security and Acceleration Server

I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.

I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.

I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
