Syncronize IIS servers in a web farm to enable ETags
It’s known that on web Farm using of eTags under IIS doesn’t work properly unless all servers are synchronized.
http://support.microsoft.com/?id=922733
suggests to
synchronize the ETag values on all the Web servers that are running IIS using
Mdutil.exe
that should be extracted from Windows CD
http://developer.yahoo.com/blogs/ydn/posts/2007/07/high_performanc_11/#comment-14835
suggests to use
iiscnfg.vbs
script (with the /copy switch) to keep cluster configuration synced up, this keeps the MDETAGCHANGENUMBER synced up too.
http://www.upgradenrepair.com/Software/Microsoft/Windows%20Server%202003/Library/I/iiscnfgvbsconfig.htm
has more details about
Iiscnfg.vbs
Finally I found extended recommendations how to synchronze IIS databases in
http://weblogs.asp.net/owscott/archive/2006/06/07/IISCnfg.vbs---IIS-Settings-Replication.aspx
It has customized
MetabaseMerge.bat
script
, that seems the most appropriate for the job.
Alternative solution is described on codeProject
Synchronize file date time on multiple IIS servers and fix ETag discrepency
