Ajax - Call An ASMX Webservice In Javascript Without Resetting Authentication Timers

Nov 23, 2010

Pinging back to a webservice in ajax from the client keeps the user's session alive, I don't want this to happen. More extensive summary For a website we're developing, we need the client to ping back (in js) to a webservice (ASMX) on the server (IIS7.5). This happens to let the server know that the user is still on the site, and hasn't browsed away to another site. This is as our customer wants to let users lock records, but if they browse away to other sites, then let other people take over those locked records. Perhaps the distinction between the client being on the site but inactive and on another site seems unimportant, but that's kinda irrelevant, I don't get to write the UI spec, I just have to make it work.

My problem is this, the ping stops the user from being timed out on the server through the standard forms authentication timeout mechanism. Not surprising as there is that 30 second ping in the background keeping the session alive. Even though we want to know if the user is still on the site, we want the normal forms authentication timeout mechanism to be honoured. I thought I might be able to fix this by removing the ASP.NET_SessionId and .ASPXAUTH cookies in the XMLHttpRequest that is the server ping, but I can't figure out how to do this. This is how my web service & method are defined:

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class PingWS : WebService
{
[WebMethod]
public void SessionActive(string sessionID)
{
// does stuff here
}
This is how I'm calling it in js (request is over HTTPS, :
$.ajax({
type: "POST",
url: "PingWS.asmx/SessionActive",
data: 'sessionID=' + aspSessionID + '}',
beforeSend: function (xhr) {
xhr.setRequestHeader('Cookie', '');
xhr.setRequestHeader('Cookie', 'ASP.NET_SessionId=aaa; .ASPXAUTH=bbb;');
},
dataType: "json"
});

I was trying with the setRequestHeader, but that just appends to the header rather than overwrites the header, and IIS is happy to ignore that junk I added. I'm thinking maybe I should be trying to do this at the server end, someone take PingWS.asmx out of the loop so that it doesn't keep the session active, but I'm not sure how to do this. Although the title of the question is focused on clearing the cookie in the header, I'd be super happy if anyone points out that I'm being really stupid and there is actually a much better way of trying to do what I'm doing.

I'm thinking at this stage maybe I need to add something to the webmethod that says how long this particular page has been inactive, and use that knowledge to timeout manually. That actually sounds pretty easy, so I think I'll do that for now. I'm still convinced that there must be an easy way to do what I originally wanted to do though. Update I'm thinking I'm pretty screwed in terms of cookie manipulation here as both the .ASPXAUTH and ASP.NETSessionId cookie are HttpOnly, which means the browser takes them out of your hands, you can't access them via the document.cookies object. So I would say that leaves me with:

Updating my SessionAlive webmethod to track each request so I can tell how long the user has been sitting idle on a page and timeout if needs be Marking the .asmx page somehow on the server end so that it's taken out of the normal authentication/session tracking flow I know how to do 1. so I'll start there but 2. seems much cleaner to me.

Security :: Not Extending MembershipProvider Class And Putting All This Methods In Some Unique Class And Call Its Methods Then?

Sep 16, 2010

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:

1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.

2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.

3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.

I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.

WCF / ASMX :: Use Asynchonous Web Methods?

Dec 23, 2010

I have an ASP.NET 3.5 web application that uses ASMX web services that are called synchronously. I want to see if I can call them asynchronously because some of the web methods take a long time to process and I'm concerned that this is affecting scalability.

I found this article that explains how to use Asychronous web methods, from 2002: http://msdn.microsoft.com/en-us/library/aa480516.aspx. It says:

For asynchronous requests, during reflection the ASMX handler looks for Web methods with a certain kind of signature that it recognizes as being asynchronous. In particular, it looks for a pair of methods that have the following rules:

There is a BeginXXX and EndXXX Web method where XXX is any string that represents the name of the method you want to expose. The BeginXXX function returns an IAsyncResult interface and takes as its last two input parameters an AsyncCallback, and an object respectively. The EndXXX function takes as its only parameter an IAsyncResult interface. Both must be flagged with the WebMethod attribute. When I create the reference to my web service, I don't see any BeginXXX and EndXXX methods. I only see a XXXAsynch method and the article doesn't mention that method. I've done further research and every other article I've found also mentions the BeginXXX and EndXXX web methods.

How To Call Methods On Object

Oct 17, 2011

I'm teaching myself web services at the moment and I've hit a bit of a stumbling block:-I've implemented a set of services for ordering shutters.These services use an underlying object model consisting of an order and a shutter class.The CreateOrder Service returns an order object and I now want to be able to add shutters to it by calling myOrder.Add(myShutter).

The problem is that the asp.net site I'm using to test it can't "see" the Add method on Order. If I browse the object tree I can see the Order Object but when I drill into it no methods are visible. Is this something to do with the way I've added th reference. edit> I just found the class in the "Reference.vb" file and aded this to it:-

Public Sub Add(ByVal Shutter As Shutter)
End Sub

Just about to test that. edit>I found this site and what he sugests fixes the problem but...I've had to add a local reference to the ObjectModel project to the web site. That seems wrong to me. It's not a web reference so how will this work in the real world. Once I actually deploy the service a project on a remote client isn't going to understand a local reference is it?

WCF / ASMX :: Multiple Web Methods In One Transaction?

Aug 20, 2010

it may sound a bit newbish question.We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)

BUT here's the real kicker. If I reverse the order of the public static function such that GetHelloList2 comes BEFORE GetHelloList1 in the code, then the GetHelloList2 works ...... it just seems like it is only firing one pagemethod event and allowign only one.

WCF / ASMX :: Returning Web Methods As Different Formats Based On Querystring?

Mar 23, 2010

I have some WCF services that I want to return in different formats based on a querystring param. For example, [URL], [URL], [URL], etc... This would make it so that many different types of clients could consume the services whichever way was easiest for them, such as binary for a .NET client and json for an ajax or Flex client.

What I'm thinking is that I can have the WCF web methods return their .NET business objects and not worry about the output mode and then have a behavior that hooks in after returning from the web method which checks the querystring for this param and either:

1. Continues returning the business objects if the mode is dotnet.

2. Converts the business objects to xml if the mode is xml and returns a string of xml.

3. Converts the business objects to json if the mode is json and returns a string of json.
