I never actually posted about 2 tiny plugins I made, once jQuery 1.3 was nearing.
Both are somehow related, they are related to Ajax (jQuery.ajax) and they provide sort of a manager to allow multiple implementations of the same feature.
Needless to say, both plugins only work under jQuery 1.3 or higher. The packages(zips) include jQuery 1.2.7pre because that's the version I used to test them when I made them. You obviously don't need to use that version.
