I've 2 copies of this site synced with Subversion. One live version and something developer version. What I love to do would be to password safeguard the developer version, utilizing a .htaccess file:

AuthType Basic
AuthName "Restricted Files"
AuthUserFile ../.htpasswd
AuthPGAuthoritative Off
Require user dev 

It is possible to method to sync this .htaccess file towards the live version with no password protection there?

I believed about something similar to

[if file exists ../.htpasswd]
  AuthType Basic
  AuthName "Restricted Files"
  AuthUserFile ../.htpasswd
  AuthPGAuthoritative Off
  Require user dev 
[/if]

or

[if currentDir = /path/to/dev/version]
...
[/if]

Finaly found the solution right here: How can I password protect dev but not live while using SVN?

If mod_setenvif is enabled it's possible to set different env vars

SetEnvIfNoCase ^HOST$ .+ unauthenticated
SetEnvIfNoCase ^HOST$ ^dev\.example\.com$ !unauthenticated
