Suporta os m\u00e9todos HTTP: - OPTIONS; - GET; - HEAD; - POST; - PUT; - DELETE; - TRACE; - CONENCT. Suporta: - Conex\u00f5es dos cliente em IPv4 ou IPv6; - Conex\u00f5es ao alvo em IPv4 e IPv6; - Conex\u00f5es todo o tipo de transmiss\u00e3o de dados TCP (CONNECT tunneling), p.e. liga\u00e7\u00f5es SSL, como \u00e9 o caso do HTTPS. A fazer: - Verificar se o input vindo do cliente est\u00e1 correcto; - Enviar os devidos HTTP erros se n\u00e3o, ou simplesmente quebrar a liga\u00e7\u00e3o; - Criar um gestor de erros; - Criar ficheiro log de erros; - Colocar excep\u00e7\u00f5es nos s\u00edtios onde \u00e9 previs\u00edvel a ocorr\u00eancia de erros, p.e.sockets e ficheiros; - Rever tudo e melhorar a estrutura do programar e colocar nomes adequados nas vari\u00e1veis e m\u00e9todos; - Comentar o programa decentemente; - Doc Strings. Funcionalidades futuras: - Adiconar a funcionalidade de proxy an\u00f3nimo e transparente; - Suportar FTP?. (!) Aten\u00e7\u00e3o o que se segue s\u00f3 tem efeito em conex\u00f5es n\u00e3o CONNECT, para estas o proxy \u00e9 sempre Elite. Qual a diferen\u00e7a entre um proxy Elite, An\u00f3nimo e Transparente? - Um proxy elite \u00e9 totalmente an\u00f3nimo, o servidor que o recebe n\u00e3o consegue ter conhecimento da exist\u00eancia do proxy e n\u00e3o recebe o endere\u00e7o IP do cliente; - Quando \u00e9 usado um proxy an\u00f3nimo o servidor sabe que o cliente est\u00e1 a usar um proxy mas n\u00e3o sabe o endere\u00e7o IP do cliente; \u00c9 enviado o cabe\u00e7alho HTTP \"Proxy-agent\". - Um proxy transparente fornece ao servidor o IP do cliente e um informa\u00e7\u00e3o que se est\u00e1 a usar um proxy.
