Hi zoppelgangers, I have several applications built 100% with python CGI scripts that I'd like to run on Zope. The reason for this are : a) For the better performance (I was worried about the scalability of CGI for high-availability and knew I had to move to FastCGI or the equivalent) b) I really really like the way Zope takes care of the CGI variable handling (ie. declaring the HTML form fields as arguments in the python method). However, I don't really want to use DTML at all. The reasons is that I find it much harder to read than pure Python. This is just a personal aesthetic thing and no criticism of Zope at all (full kudos to Digicool on an excellent application). It's just coding aesthetic : I like it all kept in Python, like servlets in java (as opposed to CFML, ASP etc). So, I've put all of my CGI scripts in a newly-created extensions directory and registered them via the Zope web-manager. It was, as the documentation says, incredibly simple and it seems to work for simple methods. (I'll declare my own packages later). Now, if I just use External Methods like this (using my own ex-CGI Python scripts to query databases, IMAP etc), am I missing out on any of Zope's main benefits ? In particular, the cache management ? Would I have to turn my stuff into a Zope Product to get these benefits ? (I've not had too much joy with the Product stuff yet) chas
