iis - IISExpress Log File Location

Question

IISExpress writes log and configuration data to pre-determined location out of the box.

The directory is an "IISExpress" directory stored in a user's Documents directory.

In the directory is stored the following folders files underneath.

• Config
• Logs
• TraceLogFiles

The location of my home directory is on a network share, determined by group policy

Currently we are encountering scenarios where visual studio locks up when stopping debugging Silverlight applications using IIS Express.

I was looking to change the location for the log & configuration data for IISExpress to see if this fixes the problem of visual studio locking up. Is it possible to change the default location of log & config files ?

Answer 1

1 . By default applicationhost.config file defines following two log file locations. Here IIS_USER_HOME would be expanded as %userprofile%documentsIISExpress.

<siteDefaults>
<logFile logFormat="W3C" directory="%IIS_USER_HOME%Logs" />
<traceFailedRequestsLogging directory="%IIS_USER_HOME%TraceLogFiles" enabled="true" />
</siteDefaults>

You can update above directory paths to change the log file locations.

2 . If you are running IIS Express from command line, you can use '/config' switch to provide configuration file of your choice. Following link may help you http://learn.iis.net/page.aspx/870/running-iis-express-from-the-command-line/
