From: Michael Wallner This function returns a valid HTTP date regarding RFC 822/1123 Compose a valid HTTP date regarding RFC 822/1123 This function returns an absolute URI constructed from url. Takes an optional unix timestamp as parameter. Build a complete URI according to the supplied parameters. If the url is already abolute but a different proto was supplied,http_functions.c
string http_date([int timestamp])

looking like: "Wed, 22 Dec 2004 11:34:47 GMT"string http_absolute_uri(string url[, string proto[, string host[, int port]]])
-
-If the url is already abolute but a different proto was supplied,

+
+Returns the HTTP date as string.string http_build_uri(string url[, string proto[, string host[, int port]]])

only the proto part of the URI will be updated. If url has no
path specified, the path of the current REQUEST_URI will be taken.
The host will be taken either from the Host HTTP header of the client
the SERVER_NAME or just localhost if prior are not available.
-
-Some examples: url = "page.php" => http://www.example.com/current/path/page.php
- url = "/page.php" => http://www.example.com/page.php
- url = "/page.php", proto = "https" => https://www.example.com/page.php

Send HTTP status code.

This converts the given timestamp to a valid HTTP date and

Send a "Last-Modified" header with a valid HTTP date.
+Accepts a unix timestamp, converts it to a valid HTTP date and
sends it as "Last-Modified" HTTP header. If timestamp is
-omitted, current time is sent.
Returns TRUE on success or FALSE on failure.
Sets the content type.
+Send the Content-Type of the sent entity. This is particularly important
+if you use the http_send() API.
Accepts an optional string parameter containing the desired content type
+(primary/secondary).
Returns TRUE on success or FALSE on failure.
Set the Content Disposition. The Content-Disposition header is very useful
+
Send the Content-Disposition. The Content-Disposition header is very useful
if the data actually sent came from a file or something similar, that should
be "saved" by the client/user (i.e. by browsers "Save as..." popup window).
Matches the given timestamp against the clients "If-Modified-Since" resp.
-"If-Unmodified-Since" HTTP headers.
This matches the given ETag against the clients
-"If-Match" resp. "If-None-Match" HTTP headers.
Expects a string parameter specifying the file name the "Save as..." dialogue
+should display. Optionally accepts a bool parameter, which, if set to true
+and the user agent knows how to handle the content type, will probably not
+cause the popup window to be shown.
Returns TRUE on success or FALSE on failure.
+Matches the given unix timestamp against the clients "If-Modified-Since"
+resp. "If-Unmodified-Since" HTTP headers.
Accepts a unix timestamp which should be matched. Optionally accepts an
+additional bool parameter, which if set to true will check the header
+usually used to validate HTTP ranges. If timestamp is omitted, the
+current time will be used.
Returns TRUE if timestamp represents an earlier date than the header,
+else FALSE.
Matches the given ETag against the clients "If-Match" resp.
+"If-None-Match" HTTP headers.
Expects a string parameter containing the ETag to compare. Optionally
+accepts a bool parameter, which, if set to true, will check the header
+usually used to validate HTTP ranges.
Retuns TRUE if ETag matches or the header contained the asterisk ("*"),
+else FALSE.
Attempts to cache the sent entity by its last modification date.
+Accepts a unix timestamp as parameter which is handled as follows:
If timestamp_or_expires is greater than 0, it is handled as timestamp
and will be sent as date of last modification. If it is 0 or omitted,
the current time will be sent as Last-Modified date. If it's negative,
it is handled as expiration time in seconds, which means that if the
requested last modification date is not between the calculated timespan,
the Last-Modified header is updated and the actual body will be sent.
Returns FALSE on failure, or *exits* with "304 Not Modified" if the entity is cached.
+A log entry will be written to the cache log if the INI entry
+http.cache_log is set and the cache attempt was successful.
This function attempts to cache the HTTP body based on an ETag,
-either supplied or generated through calculation of the MD5
-checksum of the output (uses output buffering).
-
-If clients "If-None-Match" header matches the supplied/calculated
+
Attempts to cache the sent entity by its ETag, either supplied or generated
+by the hash algorythm specified by the INI setting "http.etag_mode".
If the clients "If-None-Match" header matches the supplied/calculated
ETag, the body is considered cached on the clients side and
a "304 Not Modified" status code is issued.
Returns FALSE on failure, or *exits* with "304 Not Modified" if the entity is cached.
+A log entry is written to the cache log if the INI entry
+"http.cache_log" is set and the cache attempt was successful.
For use with ob_start().

+For use with ob_start(). Output buffer handler generating an ETag with
+
+the hash algorythm specified with the INI setting "http.etag_mode".void http_throttle(double sec[, int bytes = 2097152])
+Sets the throttle delay and send buffer size for use with http_send() API.
+
+Provides a basic throttling mechanism, which will yield the current process
+resp. thread until the entity has been completely sent, though.Note: This doesn't really work with the FastCGI SAPI.
+Expects a double parameter specifying the seconds too sleep() after
+
+each chunk sent. Additionally accepts an optional int parameter
+representing the chunk size in bytes.Example:
-
<?php
// ~ 20 kbyte/s
# http_throttle(1, 20000);
# http_throttle(0.5, 10000);
# http_throttle(0.1, 2000);

+The supplied url will be expanded with http_build_uri(), the params array will
be treated with http_build_query() and the session identification will be appended
-if session is true.
-
-Depending on permanent the redirection will be issued with a permanent
-("301 Moved Permanently") or a temporary ("302 Found") redirection
-status code.
-
-To be RFC compliant, "Redirecting to URI." will be displayed,
-if the client doesn't redirect immediatly.
The HTTP response code will be set according to status.
+You can use one of the following constants for convenience:
+ - HTTP_REDIRECT 302 Found
+ - HTTP_REDIRECT_PERM 301 Moved Permanently
+ - HTTP_REDIRECT_POST 303 See Other
+ - HTTP_REDIRECT_TEMP 307 Temporary Redirect
Please see http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3
+for which redirect response code to use in which situation.
To be RFC compliant, "Redirecting to URI." will be displayed,
+if the client doesn't redirect immediatly, and the request method was
+another one than HEAD.
Returns FALSE on failure, or *exits* on success.
+A log entry will be written to the redirect log, if the INI entry

Send an HTTP header.
+Expects a string parameter containing the name of the header and a mixed

Returns either a string containing the value of the header matching name,
+FALSE on failure, or an associative array with all headers.
Whether it sould be attempted to cache the entitity.
This will result in necessary caching headers and checks of clients
"If-Modified-Since" and "If-None-Match" headers. If one of those headers
-matches a "304 Not Modified" status code will be issued.
-
-NOTE: If you're using sessions, be shure that you set session.cache_limiter
+matches a "304 Not Modified" status code will be issued.
