Salud: i'im triying to do some little modifications in the script that shows the MARC format of the record in Koha's OPAC (opac-MARCdetail.pl). I've found that any modification in the code is not shown inmmedialely on the screen, for example if I make print "Content-Type: text/html\n\n"; print "<html><body>something</body></html>"; exit; the message is not shown at all. Only if I change the name of the script and run it works, but again the new script seems to remain "frozen" in this initial step and doesn't show any further modification. I suppose that the problem is based in the existence of some cache anywhere, I would like to know how to avoid this behaviour in order to see in real time the effect of the modifications I'm doing. Thank you very much Camilo Freire Uruguay
