DESCRIPTIONwwwoffle controls the World Wide Web Offline Explorer proxy HTTP
server.
The wwwoffle program is used to control the wwwoffled program, to tell
it when the computer is online or offline, and which URLs to get and
when to fetch them.
The control options are also available from the server on an interac‐
tive control web page at http://localhost:8080/control/.
OPTIONS
The command line options available for the program are described below.
-h | --help
A help message is printed giving a brief description of the
usage of the program.
--version
The version number of the program is printed.
-online
Tell the wwwoffled proxy server that the computer is online to
the internet and that requests are to be fetched immediately.
-autodial
Tell the wwwoffled proxy server that the computer can become
online to the internet if required for requests that are not
already cached, but that pages that are in the cache do not
require any network access. This is intended for use with dial-
on-demand systems (using diald for example).
-offline
Tell the wwwoffled proxy server that the computer is not online
to the internet and that requests are to be cached until they
are fetched later.
-fetch Tell the wwwoffled proxy server to fetch all of the requests
that have been cached. (The proxy server must be online for
this to work.) The program will wait until all of the requests
have been met before exiting.
-config
Tell the wwwoffled proxy server to re-read the configuration
file.
-dump Tell the wwwoffled proxy server to dump out the current program
configuration. This is equivalent to the most recently read
configuration file and the built-in default options.
-cyclelog
Tell the wwwoffled proxy server to close and then re-open the
log file.
-purge Tell the wwwoffled proxy server that the cache is to be purged.
The configuration file wwwoffle.conf(5) specifies the maximum
age of the pages to keep. If a maximum cache size is specified
then the oldest pages are deleted until the size is not
exceeded.
-status
Request from the wwwoffled proxy server the current status of
the program. The online or offline mode, the fetch and purge
statuses, the number of current processes and their PIDs are
displayed.
-kill Tell the wwwoffled proxy server to exit cleanly at the next con‐
venient point.
URL The URL of a web page that is to be fetched. This is the same
as using a browser and entering the URL if not already in the
cache or pressing the refresh button in the index if it is in
the cache.
file The name of an HTML file that is to be parsed and the links in
it are to be fetched as if the URLs had been specified on the
command line.
-o Fetch the specified URL (from the cache or request it if not
already cached when offline, or get it when online) and output
it on standard output. This is an easy way of getting an image
out of the cache to be used in other programs. The contents of
the ModifyHTML section of the configuration file are ignored and
the unmodified data is output.
-O Fetch the specified URL (from the cache or request it if not
already cached when offline, or get it when online) and output
it on standard output including the HTTP header. The contents
of the ModifyHTML section of the configuration file are ignored
and the unmodified data is output.
-F Force the specified URLs to be refreshed. Without this option,
the page will not be fetched unless newer than the version on
the server.
-r[<depth>]
Causes the pages linked to by the specified URLs also to be
fetched if they are on the same host. This recursion works for
a number of links specified by the depth parameter, a depth of 0
means only the specified page, a depth of 2 means all linked
pages and all links from them.
-R[<depth>]
The same as -r above, but it also works for links that are not
on the same host.
-d[<depth>]
The same as -r above, but is limited to links in the same direc‐
tory or a sub-directory.
-gS Also fetches the stylesheets that are included in the specified
URLs.
-gi Also fetches the images that are included in the specified URLs.
-gf Also fetches the frames that are included in the specified URLs.
-gs Also fetches the scripts that are included in the specified
URLs.
-go Also fetches the objects that are included in the specified
URLs.
-post Create a request using the POST method, the data is read from
stdin, and appended to the request. The user must ensure that
the format of the data is valid for a POST request. Any of the
characters '&', '=' or ';' that are not being used for their
reserved purpose must be URL-encoded in the input, other charac‐
ters will be URL-encoded.
-put Create a request using the PUT method, the data is read from
stdin and appended to the request.
-c <config-file>
Specifies the name of the configuration file that contains the
server host name, port numbers and authorisation password. This
is required for the -online, -autodial, -offline, -fetch, -con‐
fig, -dump, -purge, -status and -kill options if a password is
set. The user must have read access to the configuration file
to be able to use the command if a password is set. (See the
StartUp and LocalHost section of wwwoffle.conf(5) for more
information on setting the server host name, ports and pass‐
word.)
-p <host>[:<port>]
Sets the hostname and port number that is to be used for the
connection to the proxy server. For the -online, -autodial,
-offline, -fetch, -config, -dump, -purge, -status and -kill
options this must be the WWWOFFLE control port, for the URL
options it must be the WWWOFFLE HTTP proxy server port. If no
-p option is specified then the compile-time defaults are used.
When the -F , -R[<depth>] , -r[<depth>] , -d[<depth>] or -g[Sisfo]
options are given then they will override the options that are set in
the FetchOptions section of the configuration and not fetch any other
contents of the specified URL. For example if the fetch options nor‐
mally include images and frames then using the -gi option will only
fetch images and not frames. All page contents to be fetched must be
specified as command line options. Specifying -g without any options
will fetch only the specified URL without any of the options.
ENVIRONMENT VARIABLE
The WWWOFFLE_PROXY environment variable can be used instead of the -c
or -p options. There are three ways that the variable can be used.
1. When the variable is set to absolute pathname of a file, then
that file is used as the configuration file like the -c option
(for example /etc/wwwoffle/wwwoffle.conf).
2. The WWWOFFLE_PROXY variable can also be set to the hostname and
the port number that would be used with the -p option (for exam‐
ple localhost:8080).
3. The third possibility is to set the variable to the hostname and
the two port numbers for the WWWOFFLE HTTP proxy port and the
WWWOFFLE control port (for example localhost:8080:8081). This
way it will work with both types of commands (proxy access and
control).
