Articles/Links On .Net Pipeline And Internal Request Processing Architecture?
Oct 4, 2010
I am looking details on the internal working of asp.net architecture. The topics need to include the following:
Asp.Net Thread/Application Pools
HttpRuntime
HttpApplication - When and how it is set up.How HttpContext is set up
How objects can passed along the pipeline using HttpContext.Current.Items
Why does modification of static variables requires locks in ASP.NET(advanced)IIS 7 Integration Mode

Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.

I am using the following code in my master page:
<% Html.RenderAction("RecentArticles","Article"); %>
where the RecentArticles Action (in ArticleController) is :
[ChildActionOnly]
public ActionResult RecentArticles()
{
var viewData = articleRepository.GetRecentArticles(3);
return PartialView(viewData);
}
and the code in my RecentArticles.ascx partial view: <li class="title"><span><%= Html.ActionLink(article.Title, "ViewArticle", new { controller = "Article", id = article.ArticleID, path = article.Path })%></span></li>
The problem is that all the links of the articles (which is built in the partial view) lead to the same url- "~/Article/ViewArticle" . I want each title link to lead to the specific article with the parameters like I'm setting in the partial view.

I have a web page that loads in user-defined text from a database field into a label. This text may or may not contain HTML links (standard <a href> tags). I need a way to enumerate through the links and enable/disable certain links based on whether or not the person viewing the page is logged in or not (via a session variable).The html tags include a runat=server attribute and the text is standard formatted HTML. Since the text is being loaded into a label straight from the database, the links aren't loaded into the controls collection for the form - so, I'm not able to reference the links that way.

I have designed an application and am wondering if this is the best architecture to use and whether there is any danger.
In namespace Membership I have a public class, MembershipManager, which inherits from webservice
public class MembershipManager() : System.Web.Services.Webservice
The single public web method of this class often needs to read and write to a database.
[WebMethod()] public string DoMembershipWork(...various parameters...)
The database work is done by implementing, in the same namespace,an internal class
internal class MembershipDataAccess
which has a series of internal static methods for data access e.g.
internal static bool UpdateMembership(MembershipManager m)
The MembershipManager class accesses the data access class by calling the appropriate method with itself as a parameter e.g.
MembershipDataAccess.UpdateMembership(this);
Is this a good idea. This application will be processing many transactions simultaneously. Is there a danger of not being thread safe. Note also that sometimes the MembershipDataAccess class will return datasets to the MembershipManager class.

for years now I have had a problem with trying to design the best database design for an internal email messaging system for a website.
I would have thought that this would be a fairly easy thing to think of at this point in my development history but it still eludes me to no end.
What irratates me even more is that I would think i could find something online giving more detail about it but i have yet to find the right search term to use

I've noticed that when i switch (browse) in between internal links in mywebsite "about", "services", "home", "contact", using Mozilla Firefox browser pages are moving slightly from one side to the other.(right to left and vice versa)
Tried the same in Explorer and it's fine. Any ideas why that is happening and how to fix it?

I am currently writing a C# web service which has several methods, one of which has to receive HTTP POST requests. The first thing i have done is alter the web.config file in the web service project as below.
[code]....
But when i run this i get "The remote server returned an error: (500) Internal Server Error". If i remove the parameter, by removing the stringbuilder and byte code, as well as having no parameter in the web service, it works. So it is obviously a problem with the parameters. I actually want to send more data, and was using a string[] parameter in the web service, but this also failed.

when ASP.NET throws an application error, IIS shows the 500 HTML error, but when a WCF service throws a FaultException (IIS 500), the client gets a proper SOAP fault with error message in it.
Is there any good documentation on this request processing?

I have seen a few posts regarding this issue but not one specific to my problem and I have no ideas as to what I need to do to debug this.I have some combo boxes on an aspx pages, when I select a value from the first one, it fills the second with value and so on with the third and fourth. This works with no problems until I wrap an asp.net UpdatePanel around the combo boxes and try to "ajaxify" the whole process so the page isn't dancing around. The exact error I get is: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 404

Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.

After checking the asp.net version on the web server it seems only the version 2.0 is available and so when I browse to the site i.e. http://servername/site
then I get this error below. Should I put something in the web.config file to solve this issue?It seems the error is to do with the reportviewer control I am using.
NOTE that the ERROR is on line 117Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify configuration file appropriately.

I want to be able to (in code) tell the page to refresh at that point ignoring anything else it was going to do.
Explanation:
I have a property lets call it AllUsers
AllUsers
{
return Database.GetAllUsers();
}
Now I have put it like this because in my code I want to just use this property to browse all the users and not have to check if its null or not up to date. The problem is if my method .GetAllUsers() throws an exception e.g. database is unavailable. If this happens I want to display a message to the user and reload the page to its initial state.
e.g. something like this
AllUsers
{
try
{
return Database.GetAllUsers();
}
catch(Exception e)
{
AbortAllCodeAndReloadAndDisplayMessage(e.Message);
}
}
Now I can reload the page using Response.AppendHeader("Refresh", "0;URL=ThisPage.aspx");
but how can I abort all code? because if I use this where I have placed my method the code will run and then reload on the next page load.
Should I change by property design? I wanted to have a property which would always be valid and up to date so any code using it wouldn't have to worrie
