Well, I'll try to explain: let's look at fictitious session between
server and client:
C: GET http://ofiice.domain.com/document.html
S: 302 - http://login.domain.com/ (redirect method)
C: GET http://login.domain.com/?username=aaa&passwd=bbb
S: 302 - http://office.domain.com/afjgn39nxnx8n3f29ss/document.html
(redirect method)
C: GET http://office.domain.com/afjgn39nxnx8n3f29ss/document.html
S: gives resource content (proxy method)
Clients tries to acces some document, but server want client to be
authenticated before. Server create some session-id
(afjgn39nxnx8n3f29ss), and client should use this session-id to access
resource office.domain.com. And later, than client send this session-id.
server will proxy such request to local network server, which is not
public, and which contains 'document.html' resource.
Or another example, where client, 1 hour later, tries to access the same
document:
C: GET http://office.domain.com/afjgn39nxnx8n3f29ss/document.html
S: 302 - http://login.domain.com/ (redirect method)
C: GET http://login.domain.com/?username=aaa&passwd=bbb
S: 302 - http://office.domain.com/jh43hkjshdfsdyhskdvc/document.html
(redirect method)
C: GET http://office.domain.com/jh43hkjshdfsdyhskdvc/document.html
S: gives resource content (proxy method)
I think I could do it using mod_rewrite, but now I understand, that I
can't: in apache config file I can create rules, which will makes an
decision: redirect or proxy request of client (R and P flags).
But by using external program I can't make such decision.
And that is a problem.
