Answer 1

Since its just a question i would expect you also need an explanation and not any script.

Curl can Login perfectly to the site you mention but you need to get your parameters right.

Your URL should be pointed to : http://livearchive.onlinejudge.org/index.php?option=com_comprofiler&task=login and with the following variables

username=
passwd= 
op2=login
lang=english
force_session=1
return=B%3AaHR0cDovL2xpdmVhcmNoaXZlLm9ubGluZWp1ZGdlLm9yZy8%3D
message=0
loginfrom=loginmodule
cbsecuritym3=cbm_02099e1c_6e2810f8_97a3f622ba6c000cb557bd8458534f61&j2ffb0ca892d8cf58942dfbea23559ed2=1
remember=yes
Submit=Login

Please take note of cbsecuritym3 variable and you also need to send 2 Cookie information that look eg. mosvisitor=1; 8ca25fe06780267eef1b49296a9a99ce=249baaaba68197c9b1681e57d69c3193

If all this are properly sent you would be able to login
