Joe asked for an elegant solution. Why does everyone think that means
condensed, bizarre, and hard to read? Is that your idea of "elegant" code?
Would you like to maintain code that looks like this:
listgetat(rereplace(test,"[(?|&)]*pageNum=(\d*)","#chr(10)#\1#chr(10)#","all
"),2,chr(10))
My idea of elegance would involve having a URL object that receives a URL,
parses it, and provides a method, getVar(), from which you can retrieve any
URL variable.
getVar("numPageID")

I want to see if someone can come up with a more elegant solution to
this problem.
Given:
CGI.HTTP_REFERER will always have a URL variable, "numPageID=xxx"
which is numeric and could be any size number.
The HTTP_REFERER may or may not have other URL variables in any order,
which could be alphanumeric or numeric
The current template needs to pull the value of the "numPageID" URL
variable out of the CGI.HTTP_REFERER
I'll show my solution in another post so as not to spoil anyone's view
on this problem, not saying that mine is best, of course!
Thanks,
Joe Kelly
