Hello.

Apache configuration aside, have you captured what the client actually receives when you get the "Too many redirects" error?
If you turn on Network tracing in Developer Tools (Shift+Cntrl+I) in Firefox or Chrome, you should be able to work out what's going wrong from the response headers and body, and get a steer on what additional configuration changes are needed, and where. |

I had a similar issue! I changed LogLevel to "warn", and quickly saw that my errors were coming from bad bots, etc that were being sent to 403 [F].
I implemented an exception in my configuration to stop all rules if they were at 403, and that solved my problem.
HTH! |
