I'm testing download on a site that has many links that
contain arguments.  Unfortunately, the order of the
arguments is not consistent from page to page, so I end up
storing e.g. 

/show.pl?mode=search&input=seat&revy=bil-revyen&index=52
/show.pl?mode=search&input=seat&index=52&revy=bil-revyen
/show.pl?mode=search&revy=bil-revyen&input=seat&index=52
/show.pl?mode=search&revy=bil-revyen&index=52&input=seat

etc.  Would it be hard to make HTTrack recognize these as
being equivalent?  Or are there cases where they are not
equivalent?
