It is possible that I made a huge mistake somewhere, but for some reason my controllers are called twice. This breaks the DX_Auth captcha on Chrome, but somehow Firefox and IE can handle it.
The problem is that each controller receives a call two milliseconds apart. I used log_message () to print each key / value pair from the $ _SERVER superglobal file.
The only differences are:
1st call
'HTTP_CACHE_CONTROL' => 'max-age=0'
'HTTP_ACCEPT' => 'application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5'
'HTTP_COOKIE' => 'ci_session=a:4:{s:10:"session_id";s:32:"4be9cef4e2cdae468c7443f52a5fb3f2";s:10:"ip_address";s:13:"321.321.321.321";s:10:"user_agent";s:50:"Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+en-US)+Ap";s:13:"last_activity";s:10:"1282151409";}70b300096c8d40c60a676ac65bcb222c'
'REMOTE_PORT' => '61828'
and 2nd call
'HTTP_CACHE_CONTROL' => NULL
'HTTP_ACCEPT' => '*/*'
'HTTP_COOKIE' => 'ci_session=a:4:{s:10:"session_id";s:32:"a5bb2c98a8ff4438cef3a3fe3d5ff73e";s:10:"ip_address";s:13:"321.321.321.321";s:10:"user_agent";s:50:"Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+en-US)+Ap";s:13:"last_activity";s:10:"1282151734";}4adf1de21f9708d66b3d4bc36d0b0d92'
'REMOTE_PORT' => '61842'
There is a thread on the CI forums where someone had a similar problem, but his problem turned out to be spyware. This does not apply to me. I tried on several computers, and none of my visitors could register on the site.
