Module: Mongrel::Const
- Defined in:
- lib/mongrel/const.rb
Overview
Frequently used constants when constructing requests or responses. Many times the constant just refers to a string with the same contents. Using these constants gave about a 3% to 10% performance improvement over using the strings directly. Symbols did not really improve things much compared to constants.
While Mongrel does try to emulate the CGI/1.2 protocol, it does not use the REMOTE_IDENT, REMOTE_USER, or REMOTE_HOST parameters since those are either a security problem or too taxing on performance.
Constant Summary collapse
- DATE =
"Date".freeze
- PATH_INFO =
This is the part of the path after the SCRIPT_NAME. URIClassifier will determine this.
"PATH_INFO".freeze
- SCRIPT_NAME =
This is the initial part that your handler is identified as by URIClassifier.
"SCRIPT_NAME".freeze
- REQUEST_URI =
The original URI requested by the client. Passed to URIClassifier to build PATH_INFO and SCRIPT_NAME.
'REQUEST_URI'.freeze
- REQUEST_PATH =
'REQUEST_PATH'.freeze
- MONGREL_VERSION =
"1.1.5".freeze
- MONGREL_TMP_BASE =
"mongrel".freeze
- ERROR_404_RESPONSE =
The standard empty 404 response for bad requests. Use Error4040Handler for custom stuff.
"HTTP/1.1 404 Not Found\r\nConnection: close\r\nServer: Mongrel #{MONGREL_VERSION}\r\n\r\nNOT FOUND".freeze
- CONTENT_LENGTH =
"CONTENT_LENGTH".freeze
- ERROR_503_RESPONSE =
A common header for indicating the server is too busy. Not used yet.
"HTTP/1.1 503 Service Unavailable\r\n\r\nBUSY".freeze
- CHUNK_SIZE =
The basic max request size we’ll try to read.
(16 * 1024)
- MAX_HEADER =
This is the maximum header that is allowed before a client is booted. The parser detects this, but we’d also like to do this as well.
1024 * (80 + 32)
- MAX_BODY =
Maximum request body size before it is moved out of memory and into a tempfile for reading.
MAX_HEADER- STATUS_FORMAT =
A frozen format for this is about 15% faster
"HTTP/1.1 %d %s\r\nConnection: close\r\n".freeze
