| Module | Mongrel::Const |
| In: |
lib/mongrel.rb
|
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.
| DATE | = | "Date".freeze | ||
| PATH_INFO | = | "PATH_INFO".freeze | This is the part of the path after the SCRIPT_NAME. URIClassifier will determine this. | |
| SCRIPT_NAME | = | "SCRIPT_NAME".freeze | This is the initial part that your handler is identified as by URIClassifier. | |
| REQUEST_URI | = | 'REQUEST_URI'.freeze | The original URI requested by the client. Passed to URIClassifier to build PATH_INFO and SCRIPT_NAME. | |
| REQUEST_PATH | = | 'REQUEST_PATH'.freeze | ||
| MONGREL_VERSION | = | "0.3.13.4".freeze | ||
| MONGREL_TMP_BASE | = | "mongrel".freeze | TODO: this use of a base for tempfiles needs to be looked at for security problems | |
| ERROR_404_RESPONSE | = | "HTTP/1.1 404 Not Found\r\nConnection: close\r\nServer: Mongrel #{MONGREL_VERSION}\r\n\r\nNOT FOUND".freeze | The standard empty 404 response for bad requests. Use Error4040Handler for custom stuff. | |
| CONTENT_LENGTH | = | "CONTENT_LENGTH".freeze | ||
| ERROR_503_RESPONSE | = | "HTTP/1.1 503 Service Unavailable\r\n\r\nBUSY".freeze | A common header for indicating the server is too busy. Not used yet. | |
| CHUNK_SIZE | = | (16 * 1024) | The basic max request size we’ll try to read. | |
| MAX_HEADER | = | 1024 * (80 + 32) | 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. | |
| MAX_BODY | = | MAX_HEADER | Maximum request body size before it is moved out of memory and into a tempfile for reading. | |
| STATUS_FORMAT | = | "HTTP/1.1 %d %s\r\nConnection: close\r\n".freeze | A frozen format for this is about 15% faster | |
| CONTENT_TYPE | = | "Content-Type".freeze | ||
| LAST_MODIFIED | = | "Last-Modified".freeze | ||
| ETAG | = | "ETag".freeze | ||
| SLASH | = | "/".freeze | ||
| REQUEST_METHOD | = | "REQUEST_METHOD".freeze | ||
| GET | = | "GET".freeze | ||
| HEAD | = | "HEAD".freeze | ||
| ETAG_FORMAT | = | "\"%x-%x-%x\"".freeze | ETag is based on the apache standard of hex mtime-size-inode (inode is 0 on win32) | |
| HEADER_FORMAT | = | "%s: %s\r\n".freeze | ||
| LINE_END | = | "\r\n".freeze | ||
