Zope and IIS (again)
Hi!! After some time trying the different proposals for my question, I've learned a bit and obtained some conclusions, but now I've got some other doubts. I'll tell briefly what the problem was. I've got a server with Zope and IIS, and each has some services or pages that I want to access from outside. I put each server on a different port (80 and 8080), but I saw that some of the outside clients that try to access to the pages have firewalls that block every port except 80. So I need all communications from the outside to my server to be on port 80. I obtained two possible solutions from this list. Both of them said that I could put Zope and IIS on ports different from 80 (81 and 8080, for example) and then install some sort of proxy server that would attend the requests on port 80, ask to Zope or IIS on their ports and send the response back to the client on port 80. One of the solutions was installing Microsoft Proxy Server and the other was installing Apache an rewrite rules. I tried Microsoft Proxy Server first. It doesn't exist any more, it is now Microsoft ISA Server. I installed and configured it correctly. But this is what happens: The client makes the request in port 80. The request is attended by ISA Server, which sends another request to Zope on port 8080 or to IIS on port 81. When ISA Server obtains the response, it sends it to the client through port 80. All is fine up to now. The problem is both Zope and IIS include '<base href>' tags or absolute URLs with 'www.mydomain.com:8080' or 'www.mydomain.com:81' in the pages, so after that the client requests all the objects in the pages (images, frames, etc.) on ports 8080 and 81, and as they're blocked they are not shown properly. I can fix my Zope pages not to include those tags or absolute URLs, but not the Zope management interface or the IIS pages. So the solution I need is that ISA Server (or whatever software I install as front-end to Zope and IIS) would delete all the ':8080' and ':81's from the pages before serving them to the client, so that the client would do subsequent requests for the images, etc. on the pages again in port 80. Does anyone know how to do this in ISA Server? Or does anyone know if Apache can do it? And any other web proxy server? Thanks in advance, Igor Leturia
You need to install a Virtual Host Monster in Zope.Then Zope will return the correct href. regards Max M Igor Leturia wrote:

The answer for Zope is the "SiteAccess" product.
When "ISA" allows more complex URL rewriting, you can use a VirtualHostMonster (VHM). Otherwise, you need a "SiteRoot". There are documents on Zope.org that explain their use. I do not know an answer for IIS. Dieter
Igor, I don't know how to do it in ISA server, but using Apache I there are two commands ProxyPass /<optional path/> http://www.mydomain.org:8060/ ProxyPassReverse /<optional path/> http://www.mydomain.org:8060/ The ProxyPassReverse takes care of changing the URL's on the page for images etc. See if ISA server has a similar feature. I have had no problems with this. For Zope you will need a SiteRoot object. Again see http://www.zope.org/Members/anser/apache_zserver for more info. - Robert At 05:57 PM 4/14/2002 +0200, Igor Leturia wrote:
