View 4 RepliesI there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.

<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
It uses asp.net (webforms), bunch of jquery plugins and whatnot.
Problem: there's unnecessary HTTP request to localhost/undefined and that makes every request take ~1s longer than needed.
Question: is there any tactic to find guilty code?
Clue: undefined makes me think that there's JS involved.

if you right click a line in the code, it gives you a conditional breakpoint. Check the name of the variable that has the URL value, and set a condition when typeof URL === 'undefined' or url === 'undefined' and look at the stack
Just set breakproint at line 3400 (with no conditions). It does not go through there.

3398 // Extend the settings, but re-extend 's' so that it can be

I am using C# + VSTS 2008 + .Net 3.5 + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I want to develop an ASP.Net aspx page which has the following function,
1 It could accept 3 Url parameters param1, param2 and param3, and the request looks like this,
http://mysite.com/foo.aspx?parame1=abc¶m2=def¶m3=ghi
2 When the page is responsed to client browser, I want to display a text input and a submit button nearby in the result html page, and value of text input is the same as param1, in this sample, abc will be displayed in text box, in the browser address bar, I want to keep the original long url http://mysite.com/foo.aspx?parame1=abc¶m2=def¶m3=ghi;
3 When the user change the value in text input, and click submit button, I want to send this request again to foo.aspx, and changing the param1 value to the value which user entered in text input, and at the same time, keep values of parame2 and param3 the same as last request's response. For example, when user requests http://mysite.com/foo.aspx?parame1=abc¶m2=def¶m3=ghi, and the page displays, when user changes text input from abc to google, the new request will be http://mysite.com/foo.aspx?parame1=google¶m2=def¶m3=ghi
Any reference samples? My question is I do not know how to implement so many functions in one aspx page.

View 1 RepliesTo prevent duplicate requests (i.e. pressing F5 right after clicking a command button), I've setup my page base class to ignore the request if it's detected as a duplicate.
When I say 'ignore' I mean Response.End()
Now I thought I've seen this work before, where there's an issue, I just Response.End() and the users page just does nothing. I don't know the exact circumstance in which this worked, but I'm unable to repeat it now.
Now when I call Response.End(), I just get an empty browser. More specifically, I get this html.

I setup the following test app to confirm the problem is not elsewhere in my app. Here it is:

<asp:Button ID="btnAdd2" Text="Add 2" runat="server" /><br />
<asp:Button ID="btnAdd3" Text="Add 3" runat="server" /><br />
And here's the code behind file
using System;
namespace TestDupRequestCancellation
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Init(object sender, EventArgs e)
{
btnAdd1.Click += btnAdd1_Click;
btnAdd2.Click += btnAdd2_Click;
btnAdd3.Click += btnAdd3_Click;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
CurrentValue = 0;
else if (Int32.Parse(lbl.Text) != CurrentValue)
Response.End();
}
protected void Page_PreRender(object sender, EventArgs e)
{
lbl.Text = CurrentValue.ToString();
}
protected int CurrentValue
{
get
{
return Int32.Parse(Session["CurrentValue"].ToString());
}
set
{
Session["CurrentValue"] = value.ToString();
}
}
void btnAdd3_Click(object sender, EventArgs e)
{
CurrentValue += 3;
}
void btnAdd2_Click(object sender, EventArgs e)
{
CurrentValue += 2;
}
void btnAdd1_Click(object sender, EventArgs e)
{
CurrentValue += 1;
}
}
}
When you load the page, clicking any button does what is expected, but if you press F5 at any time after pressing one of the buttons, it will detect it as a duplicate request and call Response.End() which promptly ends the task. Which leaves the user with an empty browser.
Is there anyway to leave the user with the page as it was, so they can just click a button?
Also; please note that this code is the simplest code I could come up with to demonstrate my problem. It's not meant to demonstrate how to check for dup requests.
EDIT: Another change that will allow me to achieve the same results would be to disable all my event handlers.
I know you are all going to answer "use a debugging proxy server like Fiddler" but it's not that simple.
Here's my situation: I have some code that runs on a server, in an ASP.NET page code-behind (aspx.cs), which (among other things) establishes a connection to another server, grabs some stuff, and then formats it and returns it to the browser.
The problem is that the other server is doing the wrong thing, and so I want to be able to pass a debugging flag into the page (via the query string, e.g. ?debug=true) so that it will print out the completely raw HTTP request that it is sending to the other server so I can see what the heck is wrong. This code is running in several places so I want to be able to just pass in this flag on dev, staging, or production and just see the request, without having to figure out whether the production servers can talk to some proxy server that exists somewhere, etc.
You would think that it would be easy to do this, right? So I feel like I'm crazy or something but I looked at the reference for HttpWebRequest and its parent class WebRequest and -- nothing. No can do. You would think Microsoft would have thought of this. The closest thing is that you can access the "Headers" collection but when I tried it, it omitted some really important headers like "content length" -- so it must be "lying" to me (I know it's lying, because I know for a fact that the remote server is returning a 200 status -- the request is successful, it's just returning bad/different/wrong data)
Here is the asked-for code example:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.whatever.com");
req.Method = ... whatever ...;
... other setup for the request ...
/* At this point we are about to send the request.
What does the raw HTTP request look like? */
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
I have a web method in second.aspx,which has to be executed only if the incoming request is 'application/json'.So in my First.aspx page I am programmatically generating a Http request with content type set to 'application/json' using the following code.
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost/website1/Second.aspx");
req.ContentType = "application/json";
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
string results = sr.ReadToEnd();
