ASP.NET caching headers not coming thru in IIS 6 (but are just fine in dev, which is XP's IIS 5.1

Posted By:      Posted Date: August 30, 2010    Points: 0   Category :ASP.Net
   I have some headers I am stuffing in an ASP.NET httphandler.. They work great in our XP dev environment (IIS 5.1) but on our clients prod boxes (IIS 6.0 running SSL) we aren't getting them.. Below is more detail. Offending Code: context.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));  context.Response.Cache.SetValidUntilExpires(false);  context.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);  context.Response.Cache.SetCacheability(HttpCacheability.NoCache);  context.Response.Cache.SetNoStore();   on our dev machines (sadly XP so IIS 5.1) the headers I get back are exactly what I want Server: Microsoft-IIS/5.1  Date: Fri, 27 Aug 2010 15:17:40 GMT  X-Powered-By: ASP.NET  X-AspNet-Version: 2.0.50727  Transfer-Encoding: chunked  Cache-Control: no-cache, no-store, must-revalidate  Pragma: no-cache  Expires: -1  Content-Type: application/xml; charset=utf-8    But when I take the same code and run it in production (IIS 6.0 and over SSL) the headers are not coming across correctly at all. Date Fri, 27 Aug 2010 14:59:02 GMT  Server Microsoft-IIS/6.0  mn 1c  X-Powered-By ASP.NET  X-AspNet-Version 2.0.50727  Transfer-Encoding chunked  Cache-Control private  Content-Type application/xml; charset=utf-8  Anyways ideas would be awesome Thanks

SSRS 2008 - Fixed headers while scrolling - works fine for Matrix - but not for Table??!!


I have this feature working fine for matrix, but it does not work as expected for Table (Tablix).

I tried all over, and setting both check boxes in the 'Tablix Properties' dialog page 'Repeat header rows on each page' and 'Header should remain visible while scrolling' for both row header and column header, but none of it is working. Am I missing something?

In the properties table (F4) for text box of tablix, under 'Other' there is 'RepeatWith' - none / tablix: what is this used for? I tried this property also but I cannot get the headers fixed / visible while scrolling. I cannot get the 'column headers' repeat on each page of the report. Very frustrating...

Does anyone face similar issue? Can anyone help please? Do I need any update / download any fix? For now I have the following version installed for Visual Studio 2k8:

Tooltip for GridView Column Headers (ASP.Net)

I just wanted to add auto tooltips for my GridView headers. There are couple of ways but I don't want to use javascript and wanted to use simple 'title' attribute. It took couple of hours to get the working code supporting sortable columns. I thought it will be very useful for others. Here's the code and logic behind it.

Scrollable GridView with fixed headers in asp.net C# vb.net

In this example i am going to show how to create scrollable GridView with fixed headers which don''t get scrolled with records and stay on the top in asp.net using css, I''ve tested this code on IE7 and Firefox 2.0 , 3.5.

For this we need to add css to headers of gridview to keep them on the top.

First of all place a Panel on the aspx page from thetoolbox. Set height to 200px and width to 200px
and scrollbars to Vertical.
Now add a gridview inside this Panel and set the datasource to populate gridview.

ASP.Net Caching problem ??


I'm having a problem with an asp.net 3.0 application using a gridview to display data.  The problem seems to be that despite a brand new .selectCommand being sent to the sqlDataSource, the gridview starts displaying data from *someone else's* query.  For example, user A is logged in and will be working fine until a few page submissions later when the gridview data starts suddenly showing information that belongs to another user. 

This is my first asp.net application, though I've been working with classic asp and ADO for years so I'm used to sending a SQL string and getting back the results from that string.  Apparently there is a complex caching system which is interferring which I do not at all understand so at this point I just want to stop the server from caching any data whatsoever.  Is this possible?

Any and all help will be much appreciated!!

is the page caching?


I am just trying to understand the basics flow to the MVC framework by putting in some breakpoints in the beginning of the actions of a couple of controllers.

One break point is at the HomeController/Index action where it just returns View() of the "Welcome to MVC".  The Second break point is at a SecondController/Index action where it uses the Entity Framework and returns a View() of a list from the db.

When I run this in debug, it breaks at the points I expected when I go from Home page to the Second page controller and back to Home.  However, when I go to the Second page again, it doesn't break at all?  Is the results of the Second page being cached and how and where?  How do you trigger for it to get check if data is old?

I check to see if the persistence is done on the db, by changing the value of a field on the db side and it still did not cause it to break on that action and displays old information in the view.  I am concerned because it is displaying incorrect values on the UI.  I do not have the OutputCache attribute above this action or specified any cache on my web.config.

Thanks in advance for your time :)

Data caching c#.net


Hi Friends,


I have a large SQL Database in the server from which I can create a dataset of about 10000 rows. My question is about caching this data. Which type of data caching should I choose (Server side or Client side)? Which one will provide better performance?


Thanks in advance

House of Web Services: Mandatory Headers in ASP.NET Web Services


The ASP.NET Web Services infrastructure includes support for programming with SOAP message headers. Unfortunately, the model for handling mandatory headers is flawed in that you need to write additional code so that a Web Service will not execute when a mandatory header is not processed. This column explores a specific problem that arises when you deal with mandatory SOAP handles and presents three solutions.

Web Farms: Use Data Caching Techniques to Boost Performance and Ensure Synchronization


Performance is an important concern for any application, but becomes critical when the app is a Web Service accessed by thousands of clients simultaneously. One hardware approach to distributing Web Services requests evenly is a Web farm consisting of multiple servers. Once on a Web farm, Web Service performance can be improved by using ADO.NET DataSet objects to cache frequently accessed data, reducing round-trips to the database. Here the author describes data caching in a Web farm environment and discusses how to avoid the cross-server synchronization problems inherent in this approach.
