convert_request_date(DateString) -> ErlDate|bad_date

convert_request_date/1 converts DateString to the Erlang date format. DateString must be in one of the three date formats defined in RFC 2616.

create_etag(FileInfo) -> Etag

create_etag/1 calculates the Etag for a file from its size and time for last modification. FileInfo is a record defined in kernel/include/file.hrl.

day(NthDayOfWeek) -> DayOfWeek

day/1 converts the day of the week (NthDayOfWeek) from an integer (1-7) to an abbreviated string, that is:

1 = "Mon", 2 = "Tue", ..., 7 = "Sat".

Equivalent to lookup/3

lookup(ETSTable,Key,Undefined) -> Result

lookup extracts {Key,Value} tuples from ETSTable and returns the Value associated with Key. If ETSTable is of type bag, only the first Value associated with Key is returned. lookup/2 returns undefined and lookup/3 returns Undefined if no Value is found.

Equivalent to lookup_mime/3

lookup_mime(ConfigDB,Suffix,Undefined) -> MimeType

lookup_mime returns the MIME type associated with a specific file suffix as specified in the file mime.types (located in the config directory).

Equivalent to lookup_mime_default/3

lookup_mime_default(ConfigDB,Suffix,Undefined) -> MimeType

lookup_mime_default returns the MIME type associated with a specific file suffix as specified in the mime.types file (located in the config directory). If no appropriate association is found, the value of DefaultType is returned.

message(StatusCode,PhraseArgs,ConfigDB) -> Message

message/3 returns an informative HTTP 1.1 status string in HTML. Each StatusCode requires a specific PhraseArgs:

• 301 - string/0: A URL pointing at the new document position.

• 400 | 401 | 500 - none (no PhraseArgs).

• 403 | 404 - string/0: A Request-URI as described in RFC 2616.

• 501 - {Method,RequestURI,HTTPVersion}: The HTTP Method, Request-URI, and HTTP-Version as defined in RFC 2616.

• 504 - string/0: A string describing why the service was unavailable.

month(NthMonth) -> Month

month/1 converts the month NthMonth as an integer (1-12) to an abbreviated string, that is:

1 = "Jan", 2 = "Feb", ..., 12 = "Dec".

multi_lookup(ETSTable,Key) -> Result

multi_lookup extracts all {Key,Value} tuples from an ETSTable and returns all Values associated with Key in a list.

reason_phrase(StatusCode) -> Description

reason_phrase returns Description of an HTTP 1.1 StatusCode, for example, 200 is "OK" and 201 is "Created". For more information, see RFC 2616.

Equivalent to rfc1123_date/1

rfc1123_date(Date) -> RFC1123Date

rfc1123_date/0 returns the current date in RFC 1123 format. rfc_date/1 converts the date in the Erlang format to the RFC 1123 date format.

split(String,RegExp,N) -> SplitRes

split/3 splits String in N chunks using RegExp. split/3 is equivalent to re:split/3 with the exception that N defines the maximum number of fields in FieldList.

split_path(RequestLine) -> {Path,QueryStringOrPathInfo}

split_path/1 splits RequestLine in a file reference (Path), and a QueryString or a PathInfo string as specified in RFC 2616. A QueryString is isolated from Path with a question mark (?) and PathInfo with a slash (/). In the case of a QueryString, everything before ? is a Path and everything after ? is a QueryString. In the case of a PathInfo, RequestLine is scanned from left-to-right on the hunt for longest possible Path being a file or a directory. Everything after the longest possible Path, isolated with a /, is regarded as PathInfo

split_script_path(RequestLine) -> Split

split_script_path/1 is equivalent to split_path/1 with one exception. If the longest possible path is not a regular, accessible, and executable file, then not_a_script is returned.
