2009-09-03http: add HttpParser#headers? method
This method determines if there are headers in the request. Simple HTTP/0.9 requests did not have headers in the request (and our responses we make should not have them, either).
2009-09-02http: SERVER_PROTOCOL matches HTTP_VERSION
And it'll default to HTTP/0.9 if HTTP_VERSION is not specified (as version-less HTTP requests imply HTTP/0.9.
2009-09-02test_http_parser_ng: fix failing HTTP/0.9 test case
SERVER_PROTOCOL is actually defined as "HTTP/1.1 even though it should not be for HTTP/0.9 responses.
2009-09-01http: support for simple HTTP/0.9 GET requests
HTTP/0.9 only supports GET requests and didn't require a version number in the request line. Additionally, only a single CRLF was required. Note: we don't correctly generate HTTP/0.9 responses, yet.
2009-08-11http: add "HttpParser#keepalive?" method
This should be used to detect if a request can really handle keepalives and pipelining. Currently, the rules are: 1. MUST be a GET or HEAD request 2. MUST be HTTP/1.1 3. MUST NOT have "Connection: close" set This also reduces the amount of garbage we create by globalizing constants and using them whenever possible.
2009-08-10http: rename read_body to filter_body
This method is strictly a filter, it does no I/O so "read" is not an appropriate name to give it.
2009-08-09http: join repeated headers with a comma
Since Rack requires a Hash object, this is joined in in accordance with rfc2616, section 4.2[1]. Of course, it's up to the framework or application to handle such requests. I could optimize this to avoid creating a single garbage String object, but I don't think it's common enough to worry about... [1] - http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2
2009-08-09http: add test for invalid trailer
Just in case clients decide to get cute.
2009-08-09http: unit tests for overflow and bad lengths
We're bound by the maximum value of off_t when handling input bodies (we need to buffer to disk). Also ensure we stop bad clients that send us unparseable lengths.
