Redirector selects the mirror primarily based on GeoIP information. Therefore, it is very likely that in the current configuration, the same backend will be selected repeatedly in the case of MirrorService.org (in case both urls are accessible and updated). And that would make it impossible to use a balancer on the MirrorService.org side. The ideal solution would probably be to add the "base URL" and "backend URLs" option to the mirror configuration. A "base URL" would be used for address listing and redirection. To test the usability of the mirror, all available "backend URLs" would then be tested and the overall status of the mirror would be determined by whether at least one "backend URL" is accessible and at the same time whether all of the accessible "backend URLs" are updated. What is your opinion on this idea? This should ensure reliable operation for use with the redirector, while allowing proper use of the balancer on the MirrorService.org side. Cheers -- Slávek
