[Zope] external cgi

Hi all - I am selecting certain records from a table. Within the <dtml-in> loop, I need to execute a cgi script residing on a second server (which is not hosting zope) for each row of returned data. How?? I can't use RESPONSE.redirect, that I know of, because it does not return control to the originating zope page it was called from after executing. I've installed ZCGI, but that doesn't seem to facilitate cgi scripts on a different machine. I've tried a simple python script which imports urllib and then try's a urlopen, but that didn't work either. Has anybody had to solve a similar problem or know where I'm going wrong? Thanks in advance! Liz
