I am searching through about 20 log files approx 200 meg each. The following code is the sub whith which I actually do the searching and output the text. 
sub search_file
{
    my ($filename) = @_;
    open (TMPFILE, "$filename") or die("unable to open $filename: $!\n
+"),br;
    print h3("$_\n");
    while (<TMPFILE>)
    {
        if ( m/^....($MM1|$MM2|$MM3|$MM4|$MM5|$MM6)/)

        {
            s/($SEARCH|$SEARCH1|$SEARCH2)/<font color=\"#0000ff\"><b>$
+1<\/b><\/font>/o;
            print "$_\n",br;
        }
    }
    close (TMPFILE);
}

Basically the $MM1 - $MM6 are dates that Im searching for and $SEARCH-$SEARCH2 are Items Im searching for within those dates...

This is working fine. What Im looking to do - since this app takes somewhere between 5 and 10 minutes to finish searching all the files is to save the results and re-search on the data that has already been returned. I thought about initially dumping the search into a text file and doing the sub search ($SEARCH-$SEARCH2) within that. The trouble is there may be several people running this at once, and I dont want to create a lot fo text files on the server that I need to delete later.

How would I go about saving a sessions worth of data for possible more than one user, and forget about the saved session data once the browser session is closed? I just hate having to resubmit new search criteria, and wait several minutes for my new output, when I already have the data sitting in front of me.
