Firefox 3 ignores cache control http headers - security risk for online apps!
If a user, using Firefox 3, signs out of a web site and does not close the browser, anyone else using that browser subsequently can view the content of pages loaded by the previous user (eg in an internet cafe, or any place where workstations are shared eg universities) - exposing private/confidential data. This only affects HTTP post requests (not gets) and only Firefox version 3 - earlier versions (1.5, 2 etc), and IE, are not affected. The main points are: This is definately a bug: a violation ......

ASP.NET 3.5 controls not being rendered
For some reason some controls/tags within ASP.NET do not always get rendered/passed to the client. This has happened to me on a number of occasions. It seems limited to <style> and <script> tags - but happens for both raw HTML (within the aspx designer) and dynamically created tags (eg using new HtmlGenericControl("style")... This is happening to controls/tags within AJAX updatepanels within, webforms and usercontrols. Sometimes I can work around this by simply placing these controls/tags ......

ASP.NET event firing twice
This seems to be a very common problem where by your event handler method gets run twice. It is caused by VS.NET inserting 2 wireup of the event handler: - once in the aspx (HTML) eg: <asp:Button ... OnClick="btnTest_Click" /> - and once in the VS.NET generated section (InitializeComponent) eg: this.btnTest.Click += new System.EventHandler( The easiest solution, imo, is to simply remove the "OnClick..." HTML markup from the .aspx page. Eg change this: <asp:Button ID="btnTest" ......

Manually configure a web app dir for a specific version of the .NET framework
In some cases you may want or need to change the version of .NET that a particular web application directory uses. Normally this is done via the ASP.NET tab on the IIS properties page for the web app, however it can also be done manually at the command line... CD into the dir containing the version of .NET that you require eg: C:\WINDOWS\Microsoft.NET\Fr... Run aspnet_regiis.exe specifying the name of the dir you want this set against. eg aspnet_regiis.exe -s W3SVC/nnn/ROOT/xxx (where ......

Atlas web site templates missing from "My Templates" after Atlas installation
If you've just installed ASP.NET Atlas, and have started up VS2005, clicked File - New - Web Site... ..but, hang on... the "Atlas Web Site" template isn't there (as it should be according to the 'Setup your environment' section of the Atlas setup). In my case it appears that the original installation either had a problem (although I don't remember any issues at the time) or some how corrupt the templates or lost reference to them. Well all's not lost. To fix I did the following: Open Windows Explorer ......
