[Twisted-web] ssl verify callback called multiple times for each request

Hello, I'm wondering why the verify callback is called multiple times for each request. I get 2 invalid callbacks and 1 valid callback. The 2 invalids are errnum 18, then 26...then a valid callback. I used https://help.ubuntu.com/community/OpenSSL for ca, and signed server and client certificates. -- Kevin McIntyre | Software Engineer | *Green Charge Networks* Cell 718-249-5058 | kmcintyre@greenchargenet.com | www.greenchargenet.com
