Web based file explorer

Question

Hi all, I'm new here, but i hope you guys can help me out
I've had some good experience with DW, but on php. Now i'm
working on a company where I'm forced to use ASP, and I am quite
enjoying it.
I developed a web based file explorer, with a javascript
frame on the left with the folder tree, and mainwindow on the
right, to ease up the file download.
Basically, all i do with my script, is to send a folder
string via url like this:
www.blablabla.com/xpto/files.asp?folderref=./folder1/folder2
the script just grabs a handle on the folder
/xpto/data/folder1/folder2/ and list the files, with links, icons
for every file, last mod date, size, and file type.
My problem... I need to do a back button to do a folder up.
I'm currently using the javascript:history.back(-1) system, but
that's not very reliable since you can browse a different folder in
the tree and clicking it goes back to the last folder it was in.
other thing
i have a path string using the string passed by url, and
replacing the / by -> and . by home... I'd like to put links in
each of the folder names so it'd go directly to those folders
ie. Home -> folder1 -> folder2 -> folder3
the link in folder 2 would resolve /xpto/data/folder1/folder2
Any way to strip the string that way?
One other thing...
The file explorer tree, gets the folder structure from a
multi-dimesnional array set this way:
['Home', 'index.asp?folderref=.',
['a', 'index.asp?folderref=.',
['b', 'index.asp?folderref=.',
['c', 'index.asp?folderref=.'],
This causes me a problem... It's not as dynamic as i wanted
it to be. Is there a way to make a script that generates the folder
structure, but only needs to be run everytime the folder structure
is altered? The file structure is altered very few times. (once a
month or so)
Or
Is there a way to generate the file structure everytime the
script is run?
Which is more reliable?
Thanks in advance
Cheers
Eddy

Answer 1

If file structure updates so few times per month, I think it
is good idea to generate structure of files and folder through cron
(unix scheduler) or some kind of scheduler for windows
But if your files updated frequently it is better to generate
structure at every request to files.asp
