Urgente.

[Javier]

Necesito limitar el acceso a una página web de forma que sólo se pueda
hacer desde otra página web concreta que redirecciona a esta. Osea:
Si el navegador quiere ver la página http://xxx.xx.xx/contenido.html,
es necesario que haya entrado por http://xxx.xx.xx/entrada.html que le
redirecciona a esta. Si se pusiese en el navegador directamente
http://xxx.xx.xx/contenido.html se le deniega el acceso.
No se si se puede hacer esto por la configuración de Apache. Si es así
estaría interesado en saber como configurar el Apache para ello. Si
no, en saber como hacer la verificación en perl para que cuando se
habra la página saber de donde viene y por ello tomar las medidas
oportunas.
Muchas gracias por adelantado. Es muy urgente.
Gracias
Javier

he is thus he would be interested in knowing like forming the Apache for it.
If no, in knowing like making the verification in Perl so that when habra the
page to know themselves of where it comes and for that reason to take the
opportune measures. Thank you very much in advance. He is very urgent. Thanks

My reply:
You can't rely on $ENV{HTTP_REFERER} since it is trivial to forge.
Cookies are not always enabled on the user's browser.
You may have to use a session-id, such as
http://xxx.xx.xx/session-as873jlsd7fejtsmflksdful/contenido.html

Questions about web programming in general (not related to Perl) are
unwellcome in comp.lang.perl.misc. They are better posted in
comp.infosystems.www.authoring.cgi.

However in both groups the primary language is English and if at all
possible you should translate your question into English before
posting.
