Hi,
I've written this code which takes a specified starting page, and
iterates around every subpage, printing out the contents.
I'm slightly confused however. It is necessary to have the line
text=""; (near the very end)
Otherwise every time you refresh the page, the variable text appends
another copy of itself onto the end of the string.
How do you stop this happening (other than setting it = "" at the end)
i.e. how do you clear everything from memory once the scriptlet has been
processed?
I've tried adding this.destroy() at the end but this has no effect.
(admittedly I could just be happy with the effect of text=""; but I am
finding similar problems in other code I'm writing i.e. it works fine
the first time you run it, but the following times the variables are
clearly still stored in memory, again resulting in undesirable
behaviour).
Cheers for any help,
Chris
