I really loved you HTTP and yahoo_user classes. I stucked with writing code to automatically login on to Yahoo Japan for a week. I tried with curl, pear http_request, snoopy, etc. I found your class really worked for me. Thanks you very much. Anyway, I successfully logged in Yahoo Japan and logeged out too frequently (many times in a minute) so that I my account is locked. Since I successfully logged in, but too frequent. Do you think that it is a reason that my account was temporalily locked?
