I believe it’s in wp-content/cache/config
Thanks dhunink. I was hoping to resolve sharing the w3tc configuration, using s3fs to mount an AWS S3 bucket (it’s how I already share media uploads across servers).
I setup a symbolic link in-place of the existing master.php config file, that points to the file within the s3 bucket. This doesn’t seem to work, as w3tc blows aways the file and re-writes the entire config file.
Any suggestions for sharing w3tc cache settings across servers?
Under the General Settings tab, all down to the bottom, is a section to import and export configurations. Any reason why you can’t use that function for sharing duplicate configs?
I did googled a bit on using w3t on multi-site installations, as I’m guessing that might by your config. All the search results return the same: you can’t.
It seems a bit silly that the premier wordpress performance plugin doesn’t have a clear way to share config across a multi-server environment.
Perhaps I’ll change the plugin code itself to use my mounted s3 bucket location to store the config directly.
