Different configuration files for different webs

It is possible to have unique configuration files (one for lists and one for web parts and publishing fields) for each SharePoint web on your server. Simply create a new configuration file and append the unique ID of the web to the file name. For example:

If your web has an UID {a63cff5e-cdf5-48d0-898d-f9a24d299f06}, then its custom configuration files should have the following names:

ConfigFile{a63cff5e-cdf5-48d0-898d-f9a24d299f06}.xml

ListConfigFile{a63cff5e-cdf5-48d0-898d-f9a24d299f06}.xml

ToolsFile{a63cff5e-cdf5-48d0-898d-f9a24d299f06}.xml

ListToolsFile{a63cff5e-cdf5-48d0-898d-f9a24d299f06}.xml

Note, that this approach is useful in web part and list scenarios. For the WCM scenario, you can already set the configuration files properties through SharePoint Designer - Setting ConfigFile and ToolsFile properties for the WCM field

If you do not know the UID of the SharePoint web, we offer a simple way to get it using RadEditor for MOSS. Look at the following article for more information - Frequently Asked Questions
