"Header operations" tell that they support "condition" same as Apache's mod_headers. Apache's module supports "always" and "onsuccess" condition, but looks like OLS does not recognize "onsuccess" condition, instead creating "onsuccess" headers:
Granted, in most cases using "always" should be enough, but it seems strange to support only "always". Or support for "condition" should be dropped entirely. Or if "onsuccess" is used when there is no "always" or "always" works differently than in Apache, documentation needs to be updated accordingly.
