State Management :: Using Application_Error For Redirection / Application_Error To Redirect The User To A Custom Error Page?
Oct 11, 2010I am trying to use the Application_Error to redirect the user to a custom error page. I know I could use the web.config to do this, but let's assume for now that this is not a desirable path to take.
Initially, I tried to do a Response.Redirect to perform this, however, there seem to be occasions where the current http context does not define the response object. So, I attempted to perform a check to make sure that the response object is not null prior to attempting the redirection, and if it is not defined, perform a Server.Transfer instead.
What happens is that in most cases, the Redirect causes the browser to some generic "friendlyish" error page rather than the requested error page.
So then I tried using Server.Transfer exclusively, and this worked well for most cases, however, sometimes the transfer didn't seem to take in the browser. Changing it back to a redirect in these cases solved that problem, but reintroduced the issue where the errors previously being captured and transferred now were being redirected.
What I surmised from this is that in certain contexts where the Application_Error method is trapped, it is necessary to use Server.Transfer in redirection, whereas in others, it is necessary to use Response.Redirect. The question then became twofold: (a) When is one necessary and when is the other? and (b) What available information can I poll to tell me when a given condition exists.
After much searching, I cannot find a reasonable answer to this question. So I began to trap errors and examine the HttpContext object for some indicator. One thing that I was looking for is the reason why if even with a defined Response in the current context does a redirect fail. The only thing that stood out is that even though a Response object may exist, the Session data could be absent. I added the case to check whether the Session data was null and perform a Transfer in this case and it
seems to be handling it properly.
I emphasize "seems to be handling it properly" because no documentation I've been able to find confirms either the problem I am having or whether this is an appropriate strategy for solving it.
I guess the question is, am I on the right track here or is the null Session object just a red herring, indicative of nothing relevant. Here's the check I have set up for reference.

View 2 RepliesC# - Application Running Under A Less Privileged Account Start A Process Executing Another Application Under An Administrative Account?
Mar 9, 2011I am logged in as the administrator when I installed an application named pdflatex.exe on my server. This application works as a converter from LaTeX input file to Pdf file. I host an Asp.net MVC 3 application running under an Application Pool Identity with Load User Profile = True. The Asp.net MVC 3 code contains a code that executes pdflatex.exe using System.Diagnostic.Process instance as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = @"c:mydomain.comworking";
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.Start();
p.WaitForExit();
From the scenario above, the web application runs under a restricted acount but it executes an external application under a default account that I don't know. Can an application running under a less privileged account start a process executing another application under an administrative account?

C# - How To Determine Whether A Web Application Is Currently Running
Nov 19, 2010I have a ASP.NET web application running under IIS 6, and another process that is responsible to monitor and report status. I'd like to sample the web application by the monitoring process in order to check its status by accessing a dedicated handler on the web application, BUT i don't want to "wake up" the web application in case it is not running. Is there an option to determine whether a specific web application is currently running? if there is such an option, i would be able to first check if the application is running, and only then to access the handler to check its status.

View 7 RepliesApplication Not Running Sequentially?
Sep 30, 2010I have a web app that processes XML data. There are many steps, but to keep things simple, here are the relevant parts:
A PGP encrypted file is POSTED to my web site.I run a BATCH file to decrypt the PGP file. This batch file is run via System.Diagnostics.Process with WaitForExit set to TRUE (i.e. the decrypt process should complete before any else happens). The decrypted file is saved to a folder on my server as .XML.
Load the XML doc for processing via XmlTextReader.
I have extensive logs and ran across an exception I can't explain. While trying to load the decrypted data into XmlTextReader my app threw a System.IO.FileNotFoundException. My application is not multi threaded, so all steps should complete sequentially. I checked the timestamp of my logs when this System.IO.FileNotFoundException was encountered which as 3:00 AM. I then looked for the decrypted XML file the BATCH process should have created, and it does exist, but the file created time stamp is 3:05 AM. I can't understand why the file's created time is 3:05AM when my PGP decrypt BATCH process says it completed @ 3:00 AM.

Performance - Application Running Slow?
Feb 22, 2011There's a web app I've been assigned to, which is running very slow. It is a site that sells products so it is database driven, however even pages that do not query the database are loading very slow. The pages use master pages, and the code is in VB.NETI checked with fiddler and the time it takes to load basic (non database driven) pages are about 5.5 seconds on average.
What are some tools that can help me determine the cause of the slow speeds, and any recommendations as to how to speed it up, or potential issues that could cause it?UpdateSo I messed around with the code piece by piece as I wasn't getting anywhere with these tools. As soon as I remove master pages, and I include the same code that's on the master pages in the .aspx page itself, the speed improves drastically (approximately 5 times faster load times).What might cause the master pages to cause load times to slow down so much?

C# - LoadLibrary Call From MVC Application Running In IIS?
Mar 28, 2011I'm having trouble executing this line of code in my MVC application:

The problem is that hModule is always 0.
If I run the same code with the same value for BondProbeSettings.AssemblyFilePath but from a console application instead of the MVC app hModule is non-zero.
Are there any security issues I need to consider?
The signature for LoadLibrary is:
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
static extern IntPtr LoadLibrary(string lpFileName);

Request.LogonUserIdentity.Impersonate();
After the last line of code both: CredentialCache.DefaultCredentials and CredentialCache.DefaultNetworkCredentials are still empty.
I know that the identity is right because the following property shows the right domainuser account I'm using:
Request.LogonUserIdentity.Name => "domainuser"
This is the authentication type of that object:
Request.LogonUserIdentity.AuthenticationType => "NTLM"
