Hi,
I am running a website in a format

where only http://mydomain.com has public IP.
It is running on Apache.
Now I configured a reverse proxy to be able to reach the server where
ocw.openitup.in is hosted on Zope
what is happening is
request which is coming to a domain ocw.mydomain.com
first reaches the server mydomain.com (which has a public IP).
Then is being forwarded internally to where ocw is present like this
URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons
i.e. Apache at mydomain.com contains
ProxyPass URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons
ProxyPassReverse URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons
The best practice[1] is to use mod_rewrite in conjunction with
mod_proxy, e.g.:
RewriteEngine On
RewriteRule ^/(.*) \
URLA/VirtualHostBase/http/%{HTTP_HOST}:80/rootfolder/VirtualHostRoot/$1\
[L,P]
where the backslashes indicates that the pattern should be on the same
line. The rewrite witch can help with getting the rule syntax correct:

Just one confusion about the syntax here
HTTP_HOST will be replaced by internal IP or hostname where Zope is
serving the pages
so should I use %{ }
or replaces it by the hostname

A lot of thanks for this link.

It will be the hostname that the browser requiested (the Host: header).

Thanks a lot for telling this.If possible give me a link about this
statement.My site is actually working.
What I finally did was
URLA/VirtualHostBase/http/%{HTTP_HOST}:80/rootfolder/VirtualHostRoot/$1\
[L,P]
replaced URLA with the hostname of server which the site is requesting
and HTTP_HOST by the URL which browser requests.

[Zope] zope behind apache reverse proxy css and images broken using eduCommons
Hi, I am running a website in a format http://ocw.mydomain.com where only http://mydomain.com has public IP. It is running on Apache. Now I configured a reverse proxy to be able to reach the server where ocw.openitup.in is hosted on Zope what is happening is request which is coming to a domain ocw.mydomain.com first reaches the server mydomain.com (which has a public IP). Then is being forwarded internally to where ocw is present like this URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons i.e. Apache at mydomain.com contains ProxyPass URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons ProxyPassReverse URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons where URL_A is internal IP of machine where the site is hosted for a request to be able to reach Zope Zope documentation page says it should have VirtualHostBase and VirtualHostRoot as its path elements. Which in above format I have done. But if some one opens the domain http://ocw.mydomain.com then the CSS which is getting loaded in browser when I click view source it shows a href=URL_B/eduCommons/path/to/CSS URL_B is internal IP of server where eduCommons is running. Note that in a users browser on internet it does not show URL_A that means that request coming from internet has been able to reach what ever URL_A means in above directives. I have checked it by replacing with hostname of server on which it is running. The CSS does not loads. If I use hostname instead of URL_B then http://ocw.mydomain.com tries to load CSS, Javascrips and images from href=http://Hostname_B/eduCommons/path/to/CSS; now Hostname_B is also known only to then computers which are in my LAN. Any request on internet does know any thing about it. I checked replacing Hostname_B with ocw.mydomain.com even then the broken element in page source shows it is trying to fetch the CSS,Javascript or images from href=ocw.mydomain.com/eduCommons the above URL is in page source when client browser tries to load CSS,Javascript or image on internet. So what is happening is in the reverse proxy server which is the first place where the request are coming it is forwarded internally as URL_A/VirtualHostBase/http/URL_B/VirtualHostRoot/eduCommons what ever is present in place of URL_B that the client browser on internet is trying to load which obviously is not present. I have also checked by replacing URL_B with URL_A i.e. ProxyPass URL_A/VirtualHostBase/http/URL_A/VirtualHostRoot/eduCommons ProxyPassReverse URL_A/VirtualHostBase/http/URL_A/VirtualHostRoot/eduCommons then on a client browser on internet the CSS is being loaded from URL_A/eduCommons/path/to/CSS where URL A is again only known to my LAN and in above ProxyPass Directive it is taken from second occurrence of URL_A This URL_A string which some one is getting in a client browser on internet is again internal IP of my machine where I hosted EduCommons. -- Tapas ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Zope with Apache
I asked this question a couple of months ago but received no response, so I figured I would ask it again to see if anyone can answer the question... We are running Zope behind an Apache server. We've got things configured so that it mostly works. However, we noticed that the "breadcrumbs" list at the top of a workspace screen doesn't work correctly. For example, if I'm looking at the object /Foo/Bar/Baz, the list of items in the breadcrumbs might look like this: DTMLDocument at / Foo / Bar / Baz The links to Foo and Bar do not correctly take into account the extra item needed to tell Apache that the link goes to the Zope site. For example, the link to Foo needs to say something like http://foo.bar.com/Zope/Foo/manage_workspace instead of http://foo.bar.com/Foo/manage_workspace The tabs for the management screens work fine, however. In looking at what is happening, I believe the problem exists because the links in the breadcrumbs line are relative links. The link to "foo" would look like this: a href="/foo/manage_workspace"Foo/a instead of a href="http://foo.bar.com/Zope/Foo/manage_workspace When I open the page, the URL I give my browser is "foo.bar.com", but my Proxy settings in Apache redirect the request to "foo.bar.com:8080/Zope". When my browser sees the relative path, it prepends the "foo.bar.com" instead of "foo.bar.com:8080/Zope" because it doesn't know any better. I've managed to get around the problem by changing some code in the tabs_path_info method found in Management.py. Basically I modifed the code to prepend "BASE0" to each of the items in the breadcrumbs list. This way, I get absolute links instead of relative. However, I'm wondering if there is just some additional configuration I need to do in Apache to fix this problem without modifying Zope itself. Has anyone else encountered this and is this a bug in Zope, or is this simply a configuration issue that I need to resolve. If its a configuration issue, what would I need to change. Any help would be appreciated. Thanks. James W.

Re: [Zope] Zope with Apache
From: James Howe [EMAIL PROTECTED] We are running Zope behind an Apache server. We've got things configured so that it mostly works. However, we noticed that the "breadcrumbs" list at the top of a workspace screen doesn't work correctly. This was broken with respect to virtual hosting, as well, and the fix for that in the CVS trunk may also take care of what you're seeing. Should be in Zope 2.3 (soon, I hope).
