<insert cached-href/>

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.

Note!

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 URL. 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.

Attributes

cached-href="string"

The URL of the page to be inserted.

fetch-interval="string"

States at what interval the background process will fetch the URL and update the database.

time-of-day="string"

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.

fresh-time="string"

States how long the data for the URL in the database is considered fresh.

ttl="string"

States how long unrequested data will exist in the database before being removed.

timeout="string"

The timeout for the fetching of new data from a server.

pure-db

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 database.

nocache="string"

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.

decode-xml="string"

(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.
