It is entirely possible that I've made a huge mistake someplace, but for some reason, my controllers are being called twice. This is breaking DX_Auth's captcha's on Chrome, but somehow, Firefox and IE can handle it.
The problem is, every controller is getting called twice milliseconds apart. I used log_message() to print every key/value pair from the $_SERVER superglobal.
The only differences are:
1st Call
Code:
'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 the 2nd Call
Code:
'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 already on the CI forums where someone else had a similar problem, but his problem turned out to be spyware. This is not the case for me. I tried on several computers and none of my visitors can register for the site.
You see, DX_auth stores the value of the captcha as CI session flashdata on the first call. The second call wipes the flashdata and no one can ever get the captcha correct as a result.
Here is a sample of my access logs
Code:
123.123.123.123 - - [18/Aug/2010:12:31:26 -0500] "GET /welcome HTTP/1.1" 200 3391 "http://somewhere.com/[age" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.126 Safari/533.4"
123.123.123.123 - - [18/Aug/2010:12:31:27 -0500] "GET /welcome HTTP/1.1" 200 3391 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.126 Safari/533.4"
As you can see, the first call seems to be coming from me, and the second call has no referrer.
I thought there was a problem with the .htaccess file I used to eliminate index.php from the uri. So, I switched to the "default" .htaccess redirect as stated in the CI documentation. The double load still happens.
Code:
RewriteEngine on
RewriteCond $1 !^(index\.php|asset|captcha|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ /index.php/$1 [L]
I also used FireFox's "Live HTTP headers" plugin. Only one request is being sent by the browser and I believe it only receives only one reply.
Anybody know what's going on? Has this happened to anyone else?
