[Laszlo-dev] Dynamic library in SOLO mode

[Henry Minsky]

Yes that is right, if you modify the "href" attribute of the LzLibrary
object (that is the name  of the class which the <import> tag makes),
then that is what will be used as the URL to load from. The LZX
compiler normally supplies that value, based on the location of the
library file at compile time, but you can modify it at runtime if
you really need to.
