Class n.w.WSGIRequest(object):

When a form is POSTed, we create a cgi.FieldStorage instance using the data posted, and set it as the request.fields attribute. This way, we can get at information about filenames and mime-types of files that were posted.

Get a header that was sent from the network.

Get a cookie that was sent from the network.

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 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.

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

Get a previously-remembered URL.

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

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.

Set the HTTP response code.

Set an outgoing HTTP header.

Utility function that does a redirect.

The request should have finish() called after this.

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 CACHED to indicate that you should write no body. Otherwise, I return a false value.

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.
