t.w.c.OldRequestAdapter(pb.Copyable, components.Componentized, object) : class documentation

Gather state to send when I am serialized for a particular perspective.

I will default to calling getStateToCopy. Override this to customize this behavior.

Determine what type tag to send for me.

By default, send the string representation of my class (package.module.Class); normally this is adequate, but you may override this to change it.

We are finished writing data.

Write some data as a result of an HTTP request. The first time this is called, it writes out response data.

Get a header that was sent from the network.

Set an outgoing HTTP header.

Set the HTTP response code.

Set the Last-Modified time for the response to this request.

If I am called more than once, I ignore attempts to set Last-Modified earlier, only replacing the Last-Modified time if it is to a later value.

If I am a conditional request, I may modify my response code to NOT_MODIFIED if appropriate for the time given.

Parameters	when	The last time the resource being returned was modified, in seconds since the epoch. (type: number )
Returns	If I am a If-Modified-Since conditional request and the time given is not newer than the condition, I return http.CACHED to indicate that you should write no body. Otherwise, I return a false value.

Set an entity tag for the outgoing response.

That's "entity tag" as in the HTTP/1.1 ETag header, "used for comparing two or more entities from the same requested resource."

If I am a conditional request, I may modify my response code to NOT_MODIFIED or PRECONDITION_FAILED, if appropriate for the tag given.

Parameters	etag	The entity tag for the resource being returned. (type: string )
Returns	If I am a If-None-Match conditional request and the tag matches one in the request, I return http.CACHED to indicate that you should write no body. Otherwise, I return a false value.

Return dictionary of all headers the request received.

Get the hostname that the user passed in to the request.

This will either use the Host: header (if it is available) or the host we are listening on if the header is unavailable.

Get a cookie that was sent from the network.

Set an outgoing HTTP cookie.

In general, you should consider using sessions instead of cookies, see twisted.web.server.Request.getSession and the twisted.web.server.Session class for details.

Get my originally requesting transport's host.

Don't rely on the 'transport' attribute, since Request objects may be copied remotely. For information on this method's return value, see twisted.internet.tcp.Port.

Change the host and port the request thinks it's using.

This method is useful for working with reverse HTTP proxies (e.g. both Squid and Apache's mod_proxy can do this), when the address the HTTP client is using is different than the one we're listening on.

For example, Apache may be listening on https://www.example.com, and then forwarding requests to http://localhost:8080, but we don't want HTML produced by Twisted to say 'http://localhost:8080', they should say 'https://www.example.com', so we do:

  request.setHost('www.example.com', 443, ssl=1)

This method is experimental.

Return the text that links to a sibling of the requested resource.

Return the text that links to a child of the requested resource.

Utility function that does a redirect.

The request should have finish() called after this.

Remember the currently-processed part of the URL for later recalling.

Get a previously-remembered URL.
