I have two machines that are clustered. I am trying to dynamicly transfer
the load between the two machines. Each machine has a series of IP
address as the load gets two unbalanced an IP address is moved from one
machine to the other and I restart interchangeand have apache reread the
configuration on both machines. I hope this picture helps.
----------------- -----------------
physical IP | 166.70.62.190 | | 166.70.62.191 |
virtual IP's | 166.70.62.4 | | 166.70.62.8 |
|... various | |... various |
| IP numbers | | IP numbers |

or an other machine not part of the cluster needs to attention, repairs,
upgrades, etc. Files are transfered to the Shared Storage.
Apache-SSL Webserver Running on both machines.
Orignally I had Interchange running as localhost or 127.0.0.1. I had
problems with check-out. I changed from https://127.0.0.1 to
https://host.domain.com and it worked. Then I wanted to have multiple
https://host.domain.com for check-out because I could not get
https://127.0.0.1 to work. I interpeted that the reason it sometimes
worked and other times did not to the fact it worked when I was on a X
window on the machine but did not if I was not. I assumed (ASS of U and
ME) that I did work because I did not have a webserver on the machine I
was running the browser from. I then thought well apache can be
configured to listen on a group of IP address or host names, wouldn't it
be nice if interchange could do the same thing with out using localhost
ofr 127.0.0.1. Then I would not have problems with the multiple
check-outs. So now assume as done it to me.

I hope the above now makes things clearer, as I crawl back having shown my
ignorance. Yes, I do need to read up and understand more. Having just
one check-out to a fixed IP address/host name does work.
Thanks everyone for your enlightenment. Sorry, I was not clearer. I was
thinking that this would make a nice feature to the GUI admin for the
https checkout section.
Thank you all!
