[leonidassavvides]

Can you recommend a textbook about security of DB(MySQL only or mainly) , for example handle credit card data, passwords etc on DBs and the relevant ?

How I understand a visitor to www.??.com leaves Site and goes to other domain www.???.com ? I refer about mouse-trapping ...

Also may count by anyway currently visitors on site or time a particular visitor stay on site ?

[traq]

when you wrote "www . xx . com" were you just using it as a random example url? because in reality, it's an adult website. zzz . com is a webhost/webcalling company.
