Topic: AliasMatch problems

[fatted]

Hi,

I'm trying to map a url of the form

http://www.webserver.com/zonexx/

to a directory on the system:

/opt/share/zonexx/

Where the xx in zonexx are 2 digits (zone01, zone42,...).

So I have an AliasMatch line in my httpd.conf of:

AliasMatch ^/(zone[0-9]*)/ /opt/share/$1

However if I try to access the url say:

http://www.webserver.com/zone11/

It tries to return:

http://www.webserver.com/zone11/index.html/index.html/index.html/....

repeating the index.html 15 or 20 times...

What am I doing wrong?

Cheers!

Unlike Alias, AliasMatch does not work with just a URI prefix, but with the whole URI.

I think you want this:

AliasMatch ^/(zone[0-9]*/.*) /opt/share/$1

What's going wrong with your current regex is:

1 - your pattern translates /zone11/ to /opt/share/zone11
2 - since this is a directory, Apache appends index.html to the URI
3 - your pattern translates /zone11/index.html to /opt/share/zone11
4 - since this is a directory, Apache appends index.html to the URI (again!)
5 - your pattern translates /zone11/index.html/index.html to /opt/share/zone11
6 - etc., etc.

p.s. If "zone" must always be followed by exactly two digits, and you don't want to require a trailing slash; this might be a better regex to use:

AliasMatch ^/(zone[0-9]{2}(/.*)?) /opt/share/$1

which means $1 is "/zone followed by exactly two digits, optionally followed by (a slash followed by zero or more characters)".

Thanks for the help!

I've tried this:

Just checking .... you are using Apache 2.2, and you restarted Apache after changing httpd.conf?

I set up a similar config on Apache 2.2.4 and reproduced your exact symptoms with:

AliasMatch ^/(zone[0-9]*)/ /opt/share/$1

It worked OK with:

AliasMatch ^/(zone[0-9]*/.*) /opt/share/$1

-or-

AliasMatch ^/(zone[0-9]{2}(/.*)?) /opt/share/$1

Maybe I should try this from a different angle:

How do I get the AliasMatch to display the directory contents instead of looking for an index.html? (and spiralling off into a loop)

(Similar to say "Alias /docs/ /opt/shares/" will display the contents of the directory /opt/shares/ and not return a couldn't find index.html message).

I don't get it....

As a test, I installed Apache 2.0.58 on a Linux (Debian Etch) system and configured it with the same directory names you are using - /opt/share/zoneNN.

I still see your exact symptoms with the original regex, but either of the two regex's I proposed corrects the problem on my system.

Do you have any other Alias* or Rewrite directives which might be contributing to the problem?

One thing I noticed - be sure to clear your browser cache as well as restart Apache,
lest your browser makes it look like the new regex's don't work when they actually do.
