Solved: Access denied with code 400 (phase 2).


When I restarted my apache server. I am using the fedora 9 here.

I did not get my default page opened in browser.
When I opened the apache error log file. I saw following error.

ModSecurity: Access denied with code 400 (phase 2). Pattern match “%0[ad]” at REQUEST_HEADERS:Cookie. [id “950910”] [msg “HTTP Response Splitting Attack. Matched signature <%0a>”] [severity “ALERT”] [hostname “localhost”] [uri “/”] [unique_id “SuWoGH8AAAEAAFF3rKEAAAAA”]

I after doing some R&D but I did not got any perfect soluction.
Then I cleared the whole browser cookies. That solves my problem.

solution – clear the browser cookies…
