http://www.mydomain.com/content/123456 is parsed in a callback function.
123456 is the id of a single recordset. The callback function reads the recordset from a mysql database (not xf db) One of the recordfields contains an image url. The return value of the mediasite callback function is sth like <img src="http://.../my123456image.jpg">.
This works fine. The posted url is replaced with the returned image from the database. However, there is a problem: when I post a single media link my posting is doubled. Can this be related to any xf caching?
