ZEXP filesize
by peter bengtson 08 Dec '00

08 Dec '00

How (and if) is it possible to deduce the total size of a website from the filesize of Exported ZEXP files in Zope? If it's not possible to find a formula for the ratio of zopestuff and htmlstuff, is there any other way of getting a good estimate of "how big a site is"? Cheers, Peter

Microsoft IIS 4.0 and Zope
by Petter Enholm 08 Dec '00

08 Dec '00

Hi, This may be more of a Microsoft IIS questions than Zope question, but I give it a shot! I have installed Zope (on port 8080) on a Windows NT 4.0 server with IIS 4.0, followed to Howto that explains how to set up PCGI with IIS, and all works very well. I can access Zope through http://localhost/scripts/zope.pcgi Next step: I want to access the Zope site through a given DNS name, f eks www.mydomain.com. How can I do this with IIS 4.0? I find no way to redirect a virtual host and at the same time rewrite the URL so that the user gets http://www.mydomain.com in the browser, not .../scripts/zope.pcgi. Anybody out there with knowledge on this issue? Best regards Petter Enholm Snapper as

Could it be that you don't derive your product class (directly or indirectly) from Acquisition.Implicit? Otherwise, I'm stumped. I use just the code you describe inside the PTK, for instance.

Re: [Zope] ZNavigator

well, i installed navigator_demo.zexp and the ZNavigator folder from 2-00 and 2-01 respectively that i downloaded yesturday didn't help, but solution solution: delete navigator_demo/simple_demo/infobar/nonsens and simple_demo works your selection of objekt names, bar entries and the respective differences does unfortunately not really support bugtracking :-( since the complex_demo does not give any positive sign i give up here i would love to understand the complex_demo too, in case you have the correct version feel free to email it to me. thanks for your help and your product anyway olaf Jonas Juselius schrieb: > > Did you _install_ the code for ZNavigator 2.02 _and_ the examples in that > dist?
