Hi I installed ispconfig 3.0.3.3 on debian Squeeze. I installed too Mod security, mod evasive and ddos deflate. I use the same configuration on 3 others servers and I have no problem. With this last server when I upload a web site like concrete, it's working well but I have a error 403 when il would like to load 4 following pages quickly, when I load the fourth page I have a error 403. After I must wait for few seconds before loading another page otherwise I have the same error. I checked mod security mod evasive because this error think me that it's a problem with these modules but I didn't found where is the problem and I have no errors in apache. If you have any idea to help me please Thank you
Its most likely a problem with mod_evasive. Please try to deactivate mod_evasive and the other ddos module that you use and restart apache and check if the problem still occurs.
