How to protect application pools from session serialization exceptions?

阅读更多关于 How to protect application pools from session serialization exceptions?

问题 We're using an Out-of-Process Session Provider ( ScaleOut ) for an ASP.NET application and we've noticed that when an object that's not correctly setup for de-serialization inadvertently makes its way into session it will eventually cause the entire process to terminate . Reproducing and handling this scenario is where it gets even more interesting. The exception that terminates the process is raised in AnyStaObjectsInSessionState whose implementation is pretty straightforward: internal

Activate form authentication for CSV files in IIS7

阅读更多关于 Activate form authentication for CSV files in IIS7

问题 I have a website on IIS 7. This website has a HttpModule with an AuthorizeRequest event handler. This event does not fire for CSV files and I can access the file without logging in, I guess this is because IIS7 is not configured to require form autentication for CSV files. How can I set this? 回答1: This will impact all files, but you can add a mapping to your server configuration: Go to the properties of your website and click on "Handler Mappings". In the upper right corner click, "Add Module

jQuery Ajax Stop is not invoked (No error; 200 OK)

阅读更多关于 jQuery Ajax Stop is not invoked (No error; 200 OK)

问题 I have a working ASP.Net 2.0 code in my development server that uses jQuery Ajax. The result of the ajax call is used to load dropdown values. But when this code is deployed to a new DMZ server, the result is not getting populated in dropdown – though I am getting 200 OK as response. One obvious thing is that the Type is different in the response. It is expected as application/json but coming as text/plain . I have success call back and error callback codes. Along with this I have handlers

Why isn't my machine.config HttpModule running in my web app?

阅读更多关于 Why isn't my machine.config HttpModule running in my web app?

问题 I wrote a HttpModule in .NET 3.5, 32 bit Win 2003, IIS 6 that worked great. Its assemblies were in the GAC and the config was in the machine.config . Everything has been great for years. I just brought it all over to a new .NET 2-4, 64 bit Win 2008 R2, IIS 7.5 machine and put the same, old configuration in the machine.config . Unfortunately, the module isn't listed as those that are running on the site. When I put the configuration directly into a site's web.config , then it runs as expected.

问题 I recently embarked on the endeavor of creating my own asynchronous file upload components for ASP.NET. I took lessons learned form Darren Johnstone's FileUpload project and created an HttpModule for extracting the files from the submitted data. I got everything working as it should in testing with VS 2008 using the Development Server. I even went so far during my testing to ensure that the request was being intercepted by the module before the files began uploading. After I was satisfied

阅读更多关于 How do I attach Visual Studio 2010 to IIS 7 to debug a custom HttpModule written for an existing 3rd party web application

问题 First a little background on what I am trying to achieve. I have a client application that is utilizing REST services served by ArcGIS Server and IIS 7. I want to be able to modify the response (remove or add parameters) before the response is sent to the client. Therefore, I am developing a custom HttpModule using Visual Studio 2010 and .NET 3.5 to intercept and modify the response. However, I am having difficulty debugging my custom HttpModule. I can attach to the IIS process using Visual

IIS seems like to sleep until the next request

阅读更多关于 IIS seems like to sleep until the next request

I have created a httpModule for my Web Application which basically is triggered by a timer on specific schedules, it runs fine and the method I want is invoked after I publish it in IIS but what happens if there is no request it seems like the Web Application stops to a stand still making any scheduled events not to run, It will only run again only if I make a new request. What am I doing wrong? Can I make my website not sleep so that during times where there is no request the schduled httpModule would run as required? I hope I made this clear. You should check you Application Pool setting

Custom IIS module conflicting with gzip

阅读更多关于 Custom IIS module conflicting with gzip

As an experiment I’ve been toying with an idea of creating an IIS managed module to modify CSS files on fly. The backstory is that all out web applications keep a shared and common version number which we append to each JS, CSS and image reference (in HTML) and I wanted to modify the actual content of the CSS to also append the version number to image references in CSS. So, for instance: span.warning { background-image: url(warning-icon.png) } should become: span.warning { background-image: url(warning-icon.png?123) } Now, I know that there are many different approaches to this problem (and
