Tengo una curiosidad.
¿Puede el squid realmente acelerar un webmail? Porque cada cliente necesita una página distinta que se crea al vuelo, cada uno con su correo distinto. ¿Sirve de algo el proxy en ese caso?
Lo pregunto porque no lo se.
bueno, se podria utilizar un proxy inverso para redireccionar el trafico entrante de la gente que desea ver su correo pero que no se encuentra en la red del sitio donde trabajo....:)
Ah, espera, la clave es lo de inverso [ ... mirando wikipedia ... ] ¡Ah! Ya me entero. | A reverse proxy is a proxy server that is installed in the neighborhood | of one or more web servers. All traffic coming from the Internet and | with a destination of one of the web servers goes through the proxy | server. There are several reasons for installing reverse proxy servers: | | * Security: the proxy server is an additional layer of defense and | therefore protects the web servers further up the chain | * Encryption / SSL acceleration: when secure web sites are created, | the SSL encryption is often not done by the web server itself, but | by a reverse proxy that is equipped with SSL acceleration hardware. | See Secure Sockets Layer. | * Load balancing: the reverse proxy can distribute the load to | several web servers, each web server serving its own application | area. In such a case, the reverse proxy may need to rewrite the | URLs in each web page (translation from externally known URLs to | the internal locations) | * Serve/cache static content: A reverse proxy can offload the web | servers by caching static content like pictures and other static | graphical content | * Compression: the proxy server can optimize and compress the content | to speed up the load time. | * Spoon feeding: reduces resource usage caused by slow clients on the | web servers by caching the content the web server sent and slowly | "spoon feeds" it to the client. This especially benefits | dynamically generated pages. | * Extranet Publishing: a reverse proxy server facing the Internet can | be used to communicate to a firewalled server internal to an | organisation, providing extranet access to some functions while | keeping the servers behind the firewalls. Para balanceo de cargas no es tan obvio, ¿eh? Porque tratandose de un webmail, la conexión me da la impresión la tiene que seguir el mismo servidor web de principio a fin, y de alguna manera el proxy tiene que decidir a cual de las máquinas lo envía. No se, estoy empezando a entenderlo. ¿O buscas lo que arriba pone "Encryption / SSL acceleration"? Curioso, curioso todo esto... no lo conocía. - -- Saludos Carlos E.R. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFGOR+4tTMYHG2NR9URAtXZAJ9qZ+5mcwQkSVGVWQpaJemndoVC4gCbBo7U eun6DPODoaKE+ufMTJf+glY= =ntIY -----END PGP SIGNATURE-----
