i want to access the HTTP_REFERER server variable @ ajax call on page load event. So I have written the following code in Page_Load:
If (Request.ServerVariables("HTTP_REFERER") != null)
{
Response.Write(Request.ServerVariables("HTTP_REFERER").ToString());
[code]...
Both returns the incoming url, Just to know When to use Request.UrlReferrer and when Request.ServerVariables["HTTP_REFERER"] and why?Currently, in one of my application Urlreferrer is working in my local machine but its not working when went live?Additionally, its most appreciable if anyone can guide any alternative of both Urlreferrer and HTTP_REFERRER?
View 1 RepliesI can't figure out why I might be getting this error. It happens on an ajax call.This is the full error text:

I'm working on getting a new MVC 3.0 application up and running on a Windows 2008 server, running SQL05 and IIS7 with ASP.NET Framwork 4.0 as well as MVC installed. The index page has two select boxes. Selecting an option in the first select box does an ajax call to my controller that populatest the second select box. This works just fine on my winxp dev machine but returns a 404 on the call to the controller when running
on the server. Code for that call:
<% Html.EnableClientValidation(); %>
<% using (Html.BeginForm("CamperDirectory", "TradingPost")) { %>
Select a Season: <%: Html.DropDownListFor(x => x.SelectedSeason, new SelectList(Model.GetSeasons, "Value", "Text"),"Please select a Season.") %><br /><br />
<%: Html.ValidationMessageFor(model => model.SelectedSeason)%>
Select a Session: <%: Html.DropDownListFor(y => y.SelectedSession, new SelectList(Model.GetSessions, "Value", "Text"), "Please select a Summercamp Session.") %>
<%: Html.ValidationMessageFor(model => model.SelectedSession)%>
<input type="submit" value="Go" />
<% } %>
</asp:Content>
<asp:content ID="Content3" contentplaceholderid="HeadContent" runat="server">

I have this method in asp.net ajax enabled mvc service
[OperationContract]
public TestRun GetTestSuite(string testSuitName) {
TestRun testRun =
AdapterFactory.CreateTestRunAdapter().GetByTestSuiteName("testSuit");
return testRun;
}
Where TestRun is Created using entities framework against TestRun table. I am using following ajax method
function getTestSuite() {
$.ajax({
type: "POST",
url: "Services/TestRunService.svc/GetTestSuite",
data: '{"testSuitName" : "' + testSuiteName + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
},
//If the call fails
error: function (xhr, textStatus, errorThrown) {
alert(errorThrown);
}
})
}
I get undefined error. If I return string from service it works. Do I need to change dataType: "json" to something else?
My jQuery ajax call is failing with an undefined error. My js code looks like this:
[Code]....
My ajax source is a generic ASP.NET handler:
[Code]....
Now, if I return an empty object ("{ }") in my handler, the call will succeed. But when I return any other JSON object, the call fails.
The dataFilter handler shows that I am receiving a correct object. Firebug shows the response as expected, and the JSON tab shows that the object is parsed correctly.
So what could be the cause?
[Edit] I should have actually written "when I return any invalid JSON object, the call fails"! :D
I am making a JSON call to web method which is defined in code behind. The web method returns a class object.The class returns 3 properties one of type list and 2 integers. I am accessing these in the following manner:
success: function(result) {
alert(result);
alert(result.LookCount);
alert(result.length);
if(result.LookCount > 0)
{
var Info = "";
for(var i = 0;i < result.LookUps.length; i++)
{
Info += CreateLookUpGrid(result.LookUps[i].Client,result.LookUps[i].ClientOrg);
}
alert(result.LookCount) -> alerts undefined and when i alert result it shows me the compelte result string which has all data. So the data is returned correctly by web method. But I am unable to access it.
I found this Article from link : [URL] .... that explains how to call server-side Method from javascript,
I used your code, my server-side function is static, public, and also I added
[System.Web.Services.WebMethod]
and
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
I want to change tha value of Request.ServerVariables["Remote_Addr"],is it Possible? if yes than how can we change? if No than why we can not change?

I am trying to run this log routine in a separate thread in order to improve page load performance but I am getting an error in the line bellow: "object not set to an instance of a variable".
line error: strTempBrowser = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"].ToString();
I am suspecting that Request.ServerVariables are not available during the time that the thread executes. Is there a workaround?
Page Base Class
//STATISTICS
SiteStatisticsLite sStat = new SiteStatisticsLite();
Thread oThread = new Thread(new ThreadStart(sStat.AddLog));
oThread.Start(); // Don't wait to finish, just let stat logging to occurr after page loads
public class SiteStatisticsLite
{
//SiteStatisticsLite sStat = new SiteStatisticsLite();
I'm using IIS 7.0 on WS2008. I've implemented a simple login page that redirects to another simple page showing the Request.ServerVariables key/values. I'm using the built-in SQL membership provider. The website is on a DEV machine and there are no users on it.
When I login at the same time with 2 different users from 2 different locations (2 different public addresses) then one of the Request.ServerVariables page is the same as the other. That includes the client IP address which is then completely wrong. The authentication as well as the other cookies are wrong as well.
I checked the IIS log and it shows the correct client address as well as the correct login name. If I then reload the wrong page I get the correct data. Is there some concurrency issue in ASP.NET? I disabled the session and caching but I still get the same behaviour.
In an asynchronous process, I need to get the name of the domain/server the web application is running on. But in that situation HttpContext.Current is not available, so I cant use HttpContext.Current.Request.ServerVariables("SERVER_NAME").
View 7 RepliesModal not showing up when show is called, also error on loading page. Attaching code below, can anyone help me discover my syntax / logic issues here?
NOTE: Did some research on this before posting, some claimed it can be an issue of where the modal is placed on the page in relation to the update panel I am using. I have tried different placements of the modal extender and I also tried removing the update panel all together in hopes to at least see the modal show, no go...same issue. So with that, the issue shouldnt be around the use of the update panel...

when i was working with IIS 6.0 and windows 2003 Request.ServerVariables["LOGON_USER"] is giving me the current logged in user id,
but now we have upgraded to IIS 7 and Windows 2008 if i use the same statement it is not returning me any value.
NOTE : i am using vs2005 to write my programs.
I have a feeling that Request.ServerVariables("AUTH_USER") and User.Identity.Name return the same string while using FormsAuthentication.So my question is as simple as that. Which one should i better use?
View 1 RepliesI am developing an internal application in .NET which tracks computer name and give access only if they match users which are in a users table in database. When i tested in my local machine and in production server, I am able to get computer name. But for few users the application just don't work since Request.ServerVariables["REMOTE_USER"] is returning empty values. For myself and even for few users we can get computer name with Request.ServerVariables["REMOTE_USER"] but for few users it returns empty values.I even tried using Request.ServerVariables["LOGON_USER"] and WindowsIdentity funtions, but still getting empty values.
View 3 RepliesI'm not using any built in authentication mechanism, just building a simple intranet site that requires logon.BUT i was asked to retrieve the current windows logon name of the user, and authenticate him with this information.When reading the Request.ServerVariables("LOGON_USER") information from my box, everything runs fine. But this value is always blank when the application is running with IIS on my server.

We've added a new column to a database table. The column is defined as follows:
Name: DisplayAsSoldOut
Type: Boolean
NOT NULLABLE
Default Value: 0
We've refreshed our EDMX data model and the new column appears just fine. We are on an ASP.NET 4.0 platform using C#.
We have a class defined as PagedList which inherits from List and implenents an interface IPagedList
Within the PagedList we have the following method:
[Code]....
When we reach the following line:
{ AddRange(source.Skip((index) * pageSize).Take(pageSize).ToList()); }
we receive the following Exception ...
Type: System.Data.EntityCommandExecutionException
Inner Exception: "Invalid column name 'DisplayAsSoldOut'."
I've tried searching for this type of exception but to no avail. The column appears in the EDMX dataset just fine. I even created a small throwaway program and imported the EDMX to do a simple read from the database and it worked fine. Has anyone run across something similar?
I have the below code. When in the first time go to the if statement and return is executed. It will remain in this form. But later when return is not reached after several save button is clicked ( if statement is false), CallChildAction has not done anything without prompting error. It should return to previous form with refreshing the previous form. Do you have this experience and Do you know how to fix?
protected void btnSave_Click(object sender, EventArgs e)
{
if( .....)
return;
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "call_parent_refresh", "CallChildAction('" + Request.QueryString["chld_id"].ToString() + "');", true);
}
when svc.getLookupList(reqobj) will call i get following error.
"There was no endpoint listening at http://rets.newjerseymls.com/rets that could accept the message. This is often caused by an incorrect address or SOAP action."
