 sunlabs.brazil.proxy.CookieFilter
| CookieFilter | | public class CookieFilter implements Filter(Code) | | The CookieFilter keeps a
record of all the browser cookies associated with a given session.
This can be
used to make the user's cookies "mobile" as follows. A user's cookies
are normally stored with the browser being used, on the user's machine.
If the user runs a different browser or goes to a different machine, the
user's cookies will not be there. Instead, the user can access the web
via a proxy that keeps all their cookies. No matter which browser the
user chooses or machine the user is at, a proxy running with the
CookieFilter will automatically remember and add in their
appropriate cookies. The CookieFilter also supports
multiple, concurrent users, keeping each user's cookies separate.
- All "Set-Cookie" HTTP response headers are filtered out and saved in
the local storage. "Set-Cookie" headers are not transmitted back to the
client.
- Requests from the client have the appropriate "Cookie" headers added.
- Users can retrieve, edit, and delete their own cookies.
- JavaScript code that sets cookies is not handled by this
filter, since the code only runs on the client computer, not on the proxy.
For instance:
document.cookie = "userid=778287312". Any and
all Javascript is passed unchanged by this filter.
- This filter works in both a session-based and a non-session-based
fashion. If sessions are used, cookies are kept with respect to the
session associated with a user. If sessions are not used, all cookies
are kept in one pile for all users. The latter case is valid if, say,
only one user is using the proxy running the
CookieFilter.
Properties:
- session
- The request property to find the session id.
Defaults to "SessionID"
- nosession
- The name of the session to use if no session
id is found. defaults to "common".
- admin
- A URL prefix that causes status information to
be placed in the request properties.

| filter | | public byte[] filter(Request request, MimeHeaders headers, byte[] content)(Code) | | Returns the original content, since this filter does not change
content; it changes the headers.
|
| shouldFilter | | public boolean shouldFilter(Request request, MimeHeaders headers)(Code) | | Saves all "Set-Cookie" headers from the target in the client's local
storage, then removes those headers before allowing the response to
go back to the client. The client never sees cookies on their local
machine.
