Hi, I've been able to put together an HTML page that calls on a cgi program (via ksh) to do some server side processing, then send it back to the user's browser window. The script basically tails a log file and refreshes every # seconds (user chosen) by using the "refresh" meta tag (html).
My problem is, I want the script to be able to timeout after a certain amount of time but am not sure how to approach this. Since the meta tage causes the page to refresh automatically, I cannot use a loop to count for a timeout session. I was thinking of going with some sort of javascript (not too familiar with it) in order to take care of the refresh and timeout. Does anyone have any suggestions or ideas they can throw my way? I'd really appreciate any help that I can get on this. My code is below if anyone wants to make any suggestions (structural criticism is very welcome):
Code:
#!/bin/ksh
echo "Content-type: text/html"
echo
PATH=/usr/local/kccmds:$PATH
refresh=`echo $QUERY_STRING | cut -d"&" -f3 | cut -d"=" -f2 | cut -d"-" -f2`
echo "<HTML>
<HEAD>
<TITLE>`KCSUN Region Tails` Region Tail</TITLE> </HEAD>
<PRE>
<meta http-equiv="refresh" content="$refresh; URL=d3tail.cgi">
</PRE>
<BODY>
<BR>"
#
region=`echo $QUERY_STRING | cut -d"=" -f2 | cut -d"&" -f1`
tail1=`echo $QUERY_STRING | cut -d"&" -f2 | cut -d"=" -f2`
check=`echo $QUERY_STRING | cut -d"&" -f2 | cut -d"." -f2 `
if [ "$refresh" = "x" ]; then
refresh_msg="page refresh has been deactivated."
else
refresh_msg="which refreshes every $refresh seconds,"
fi
region_dsp=`echo $region`
typeset -u region_dsp
if [ "$check" = "err" ];
then
buffer="sys/"
tail1="unikixmain.err"
elif
[ "$check" = "log" ];
then
buffer="sys/"
tail1="unikixmain.log"
else
buffer=""
