Provided by module: Tags: Insert cached href
This tag inserts the contents of the provided URL,
as read from a database.
The database is updated repeatedly in the background by a background
process that is initiated and run as soon as this module is
loaded. If the database is empty when the tag is executed, the
standard behavior is to fetch the data immediately. When providing
values for the attributes fetch-interval, fresh-time, ttl,
update-interval or timeout, the time can either be seconds, minutes,
hours or days. If only a number is provided, it is interpreted as
seconds, otherwise write the corresponding letter or word after the
number, e.g: 10 days, 10d, 10 h, 10hours, 5 min, 5m, 2 hours and so
on. Spaces between the number and the word are allowed. The values
at the settings tab for fetch-interval, fresh-time, ttl and timeout
are the standard values that the tag will be assigned if an
attribute is left out. update-interval on the other hand, is central
and common for all tags.
The data in the database for an URL is always shared by all tags at
the same site. This means that when data for an URL is updated this
affects all tags referring to this specific URL, even if the other
attributes may differ. For example, if the same URL is referenced
by one tag without the pure-db attribute and another tag WITH the
pure-db attribute, the only guarantee is that the tag with the
attribute pure-db never will generate a data fetch. The tag without
the attribute still can.
Another implication of the data being shared is for example if the
same URL is referenced by two tags with different fetch
intervals. The data will then be updated at the smallest of these
two fetch intervals. Providing the time-of-day attribute will
however always make the module fetch data when that time of day
occur, without interference by any other tag referencing the same
Also important to note, is that since the fetching of the common
data is performed centrally by the module, the timeout of every tag
can not be used, of course. If several tags refer to the same URL
but are provided with different timeouts, the longest timeout will
be used. However, if there exists no data in the database for the
URL of a tag when the tag is run, and the pure-db attribute is not
provided, then the fetching of data will be performed for that
specific tag and with the specified timeout.
The URL of the page to be inserted.
States at what interval the background process will fetch the
URL and update the database.
Can be provided as an alternative to fetch-interval, if a fetch should
be performed once per day at a specific time. The provided time must be
of the format hh:mm.
States how long the data for the URL in the database is considered fresh.
States how long unrequested data will exist in the database before being
The timeout for the fetching of new data from a server.
If provided, the tag will only return data stored in the database, i.e
never fetch data immediately if the database is empty. Instead, the
data will not be available until the background process has updated the
If provided the resulting page will get a zero cache time in the RAM cache.
The default time is up to 60 seconds depending on the cache limit imposed by
other RXML tags on the same page.
(DEPRECATED. All text content is now decoded automatically.)
If provided the resulting content will be decoded to the internal
charset representation by looking at a potential BOM (Byte Order
Mark) and the specified encoding in the XML header. Defaults to UTF-8
if no BOM or encoding was found.
List of extra headers to send in the request. Headers are separated by comma
by default, but the delimiter can be changed using the 'header-delimiter'
Delimiter to use with 'request-headers', defaults to comma (",").
