Chapter 15. Apache 193

15.3.67. MetaDir

MetaDir speciﬁes the name of a directory where your Web server should look for ﬁles containing

meta information (extra HTTP headers) to include when serving documents.

15.3.68. MetaSuffix

MetaSuffix speciﬁes the ﬁlename sufﬁx for the ﬁle that contains meta information (extra HTTP

headers), which should be located in the MetaDir directory.

15.3.69. ErrorDocument

By default, in the event of a problem or error, your Web server outputs a simple and usually cryptic

error message back to the requesting client. Instead of using the default, you can use ErrorDocument

to conﬁgure your Web server so that it outputs a customized message or redirects the client to a local

or external URL. The ErrorDocument directive simply associates a HTTP response code with a

message or a URL which will be sent back to the client.

15.3.70. BrowserMatch

The BrowserMatch directive allows your server to deﬁne environment variables and take appropri-

ate actions based on the User-Agent HTTP header ﬁeld — which identiﬁes the client’s browser. By

default, your Web server uses BrowserMatch to deny connections to speciﬁc browsers with known

problems and also to disable keepalives and HTTP header ﬂushes for browsers that are known to have

problems with those actions.

15.3.71. Location

Location and /Location tags allow you to specify access control based on the URL.

The next use of Location tags is located within IfModule mod_perl.c tags. These conﬁguration

directives are in effect if the mod_perl.so DSO is loaded. See Section 15.4 for more information

about adding modules to Apache.

The Location tags name the /var/www/perl directory (an Alias for /perl) as the directory from

which Perl scripts will be served. If a document is requested with an URL containing /perl in the

path, your Web server will look in /var/www/perl/ for the appropriate Perl script.

Several other Location options are commented out in your httpd.conf ﬁle. If you want to en-

able the functionality they provide, you will need to uncomment the appropriate section of directives.

Note

The put module is no longer distributed as part of the Apache package. You will have to load the

mod_put package separately.

Immediately after the Perl directives is a section of directives for enabling http put (used by Netscape

Gold’s publish feature), which can post webpages to a Web server. If you want to allow http put, you

will need to uncomment the following lines:

#Alias /upload /tmp

Location /upload

# EnablePut On
