http://www.mcse.msYou can store your session in a SQL Server such that your web servers all
access the same store, however you have to note that everything you store in
the Session needs to be serialisable for that to work.

State Server can also do the job for clustered servers.
ASP.NET applications support maintaining session state on a
centralized session state server *or* on a server running SQL Server.
Because the session state is managed centrally,
any cluster host can recover session state information.

Eric, please see my just-sent reply.
You can also use ASP.NET's State Server to maintain state in a cluster.
...and, please fix your clock.

Do you have any thoughts as to when to use one and when to use the other...?
There's a fair bit of information on the net about each individually, but
there doesn't seem to be much on which is the more suitable according to
infrastructure etc...
Thanks Juan!
What about implementation of cookies? I doubt cookies has the hassle of
sessions in a web cluster.
Since we are doing it for a company and the company is very strict about its
intellecutal properties; i doubt they are going to let us lay a finger on
their servers.

Couldn't you ask an easier question ?
That's a tough nut to crack.
:-)
All in all, I think it would depend on the size of the cluster.
Small and medium-sized clusters could probably make do with State Server.
For very large, and I mean *very* large, applications in large clusters,
redundant SQL Servers are called for.
That would mean : "a cluster of SQL Servers keeping state for a cluster of w
eb servers".
The scalability of *that* configuration runs into many millions of hits dail
y.
Caveat : when using SQL Server mode, objects stored in session state
are serialised and deserialised when a request is processed.
You cannot store objects which do not support serialisation in session state
,
if you use SQL Server, so that's something to keep in mind when programming.

Will clustering of webservers affect SESSION states?

Is there a dotnet term for the above mentioned scenario?

Pls advise.

StateServer cannot be clustered, so it introduces a single point of failure,
making any cluster in front of it rather moot ;-)

Yes. That's why I said that it's only good for small/medium websites
( which don't require clustered web servers... )

StateServer cannot be clustered, so it introduces a single point of failure, making any cluster in
front of it rather moot ;-)

Yes, it will. Look into two options:
1) ASP.NET State Server
2) SQL Server Session State option

Web service - how to?

Hi
I would like to access an ms access database located at a web site from my
desktop via web service. Is there some information available on how to do
that? Would the web service run on a shared hosting web account?
Thanks
RegardsWhere ever the web service is running will have to have file level access to
the DB, is this possible with your setup?

Think of a web service as a special purpose web page with a predefined
URL and output. Let's say you wrote an ASP page that would take an ID
from the URL, get some data from the database and display it on the
screen. Now, take the URL and replace it with a special XML string,
and wrap the result up the same way and you have a web service.
The Web Service code is just another ASPX page (with a different
extension and a few more lines of code). Therefore, whatever you would
need to do to get to the database in an ASPX page, you would need to
do in a web service.

Web service or vbscript?

The project I work on is a forum. Here is a scenario: if someone replies to a topic people who are listening to the topic should be notified via email. The email should be personally addressed. (Hello <user name>, new reply for topic. Click here to go to forum reply...). Anyway I have to query the database, get the list of people subscribed for the topic and send the individual emails out. Another requirement is that this should be independent of my web page processing. I would not want my processing to block for the task to complete.

Should I rely on a web service or just plain vbscript to do this?

If I am using a web service how do I call it during web page processing? (And it should be asynchronous too...!)

Regarding VbScript VS WebService, use a web service.

Regarding if it should be async, it should.

Regarding how to call it, see this article...

Asynchronous Web Services

http://www.informit.com/articles/article.aspx?p=29395&seqNum=1

...or any of the other many fine articles on the web.

HTH.

Thank you.

Hi,

As far as I know, WebService is better. To implement Asynchronous Web Services, there is a sample as below.

WebService (name: WH)

using System;using System.Web;using System.Web.Services;using System.Web.Services.Protocols;[WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]public class Service : System.Web.Services.WebService{public Service () {//Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod]public voidSendMail() {//put your codes about sending mail into here. }}

 In your aspx page, you can call the WH WebService with Asynchronous approach.

 
protected void WSSendingMail() { WH.Service someWS =new WH.Service(); System.AsyncCallback cb =new AsyncCallback(showmsg); someWS.BeginSendMail(cb, someWS); }void showmsg(IAsyncResult ar) { WH.Service someWS = (WH.Service)ar.AsyncState; someWS.EndSendMail(ar); }
 

Hope this can help.

Web Service question

I need to get data from a database that is on a PC connected to the internet via DSL.
I've written an asp.net application that gets data from a database through a web service. This is fine as long as the database is located on the web server with the application. Now I need to get data from a database on a PC connected to the internet via DSL. The PC is not a web server, just a PC running Windows XP.
Should the web service be located on the web server? If so, how does it find the database in order to connect to the database?
Should the web service be located on the PC? Since the PC is not a web server, the web service is not advertised, so how do I create the web reference in the application?

I don't know why you posted this post about Web Services in this forum and how IT was approved in this forum.

Please post in the XML Web Services section. You well get better replies.

Regards

The webservice has to be on a server.
The database has to have access to the internet (port must be open)
The webservice has a connectionstring, which points to the database.
A webservice can make a WSDL-file, which describes the webservice.Under 'project' in visual studio, you can import it to use in yourapplication.
