ASP.Net: App_Offline.htm as a Maintenance Page

Greg — Fri, 16 Sep 2011 15:40:35 +0000

While Googling about, I came upon an oldy-but-goody, that apparently has been available since the release of ASP.Net 2.0: App_Offline.htm.

An undocumented feature, you can copy a file called app_offline.htm into the root of your .Net website and the application will “bleed off” existing connections and redirect all new requests to the app_offline.htm page.

Once you remove the file, requests will again go back to your site.

Here’s ScottGu’s posts about it from back in 2005:

One thing to note if you are using ASP.Net MVC. Be sure your system.webserver configuration is set up to handle all requests so you don’t get 404s instead of the app_offline.htm page:

runAllManagedModulesForAllRequests="true" />

WordPress on Windows with IIS7 and FastCGI PHP Upgrade Error

Greg — Sat, 12 Feb 2011 23:57:08 +0000

If you are running WordPress on IIS7 and are having trouble updating your plugins and/or WordPress itself, you might have an impersonation setting problem. Check your PHP error log (sometimes in C:\temp). If you see and error message like:

“PHP Warning: touch(): Unable to create file /tmp/wordpress-3.tmp because No such file or directory in…”

it probably means you have fastcgi.impersonate set to 1 in your php.ini and the anonymous user, IUSR, doesn’t have the rights to modify files in your site directory.

To fix this, right-click on the website directory and select Properties. On the Security tab, add the IUSR with Modify permissions. Be sure to click Advanced after and choose to replace permissions on the sub-folders.

Binding Apache and IIS both to Port 80 on Different IPs / Same NIC

Greg — Fri, 25 Sep 2009 03:39:30 +0000

If you need to run IIS 6.0 and Apache 2.2.* side-by-side on the same Windows server machine, you most likely are trying to bind apache to one IP address and IIS to another. If you have multiple IPs bound to the same NIC, this will only work if you do some tweaking to IIS’s metabase via httpcfg.exe.

The httpcfg utility is found on the installation CD in the Suppot/Tools directory in the Support.cab file (you can use WinRAR or the like to extract it).

Once you have httpcfg on your system, you force IIS to bind only to specified IP addresses with a command like:

httpcfg set iplisten -i xxx.xxx.x.x

Here’s the KB that shows in detail you how to get it done:

Hope this helps!

Recycle an Application Pool from the Command Line

Greg — Tue, 02 Oct 2007 01:08:55 +0000

Sometimes it is a whole lot nicer to recycle the specific Application Pool of concern rather than recycling IIS with “iisreset”.

There is a handy script in %windir%\system32 called iisapp.vbs and you can just run :

D:\>C:\WINDOWS\System32\iisapp.vbs /a “My Pool” /r

Connecting to server …Done.

Application pool ‘My Pool’ recycled successfully.
