I apologize (in advance) if this is on the wrong list but some of the previous discussions regarding these topics have been done here. I have read much of the documentation on Squid, the zope.org cluster configuration, and many of the excellent How-To's out there. However, my particular case requires ssl for authentication to the ZMI. It appears that ssl is best accomplished with Squid, however we have to be able to provide many of the services that the zope.org cluster leverages with LVS. It appears that the Apache+mod_proxy+ZEO configuration provides much of the functionality that Squid+ZServer would provide, alone. I guess my biggest problem is determining whether it makes sense to use Squid in conjunction with ZEO (which we want to pursue) or re-build Apache with mod_ssl in the LVS+Apache+mod_proxy+ZEO setup?? If any one has been down this road I would greatly appreciate any insight that you might have. Thanks in advance... Eric
