I just ran into a bit of a conflict with Alias and Rewrite on my front
end.
Given that I have multiple virtual hosts serving up the same content
using a slightly different set of graphics and templates, the easy way
is to "Alias /_pageparts /real/page/parts/directory" and make the
alias different for each virtual host. Then every document refers to
/_pageparts/XXX.yyy for the component it wants, and the proper one
based on the virtual host is used.
Something like this:
<VirtualHost 204.117.82.12>
ServerName next.morebusiness.com
RewriteEngine On
RewriteOptions 'inherit'
# handle GIF and JPG images directly
RewriteRule \.(gif|jpg|png|css|txt|cgi)$ - [last]
RewriteRule ^/cgi-bin - [last]
# pass off everything but images to the heavy-weight server via proxy
RewriteRule ^/(.*)$ http://localhost:4079/$1 [proxy]
DocumentRoot /web/morebusiness/nextdocs
Alias /_pageparts /web/morebusiness/nextdocs/_pageparts-default
</VirtualHost>
and on the back-end
Listen 4079
<VirtualHost localhost:4079>
ServerName next.morebusiness.com
Port 80
DocumentRoot /web/morebusiness/nextdocs
DirectoryIndex index.brc index.shtml index.html
Alias /_pageparts /web/morebusiness/nextdocs/_pageparts-default
</VirtualHost>
One of the objects inside _pageparts-default is PAGEFOOT.shtml. If I
do a
lynx -source 'http://next.morebusiness.com/_pageparts-default/PAGEFOOT.shtml'
The page comes across fine. If I do
lynx -source 'http://next.morebusiness.com/_pageparts/PAGEFOOT.shtml'
I get the page dumped raw. That is, the SSI constructs are ignored.
If I enable .shtml files to be server-parsed on the front-end server,
then both return the processed result. This is my work-around.
This leads me to believe that the Rewrite engine is ignored when an
Alias kicks in, otherwise the *.shtml files would be bounced back to
the back-end server where they get properly expanded. Normally, this
is ok for me since everything else in the aliased directory is an
image which I want the front end to handle.
Has this bitten anyone else? Stas, I think you should mention this in
the guide somehow as something to watch out for when using the proxy
front-end. The Rewrite rules are ignored when an Alias expands the
URI, or so it seems from where I sit.
