Just put the required username and password into the URL, -## as with -## webget 'ftp:/user:password@ftp.somesite.com/pub/pix/babe.gif -## ^^^^^^^^^^^^^ -## Note the user:password is separated from the hostname by a '@'. -## -## You can use the same kind of thing with HTTP, and if so it will provide -## what's know as Basic Authorization. This is >weak< authorization. It -## also provides >zero< security -- I wouldn't be sending any credit-card -## numbers this way (unless you send them 'round my way :-). It seems to -## be used most by providers of free stuff where they want to make some -## attempt to limit access to "known users". -## -## PROXY STUFF -## -## If you need to go through a gateway to get out to the whole internet, -## you can use a proxy if one's been set up on the gateway. This is done -## by setting the "http_proxy" environmental variable to point to the -## proxy server. Other variables are used for other target protocols.... -## "gopher_proxy", "ftp_proxy", "wais_proxy", etc. -## -## For example, I have the following in my ".login" file (for use with csh): -## -## setenv http_proxy http://local.gateway.machine:8080/ -## -## This is to indicate that any http URL should go to local.gateway.machine -## (port 8080) via HTTP. Additionally, I have -## -## setenv gopher_proxy "$http_proxy" -## setenv wais_proxy "$http_proxy" -## setenv ftp_proxy "$http_proxy" -## -## This means that any gopher, wais, or ftp URL should also go to the -## same place, also via HTTP. This allows webget to get, for example, -## GOPHER URLs even though it doesn't support GOPHER itself. It uses HTTP -## to talk to the proxy, which then uses GOPHER to talk to the destination. -## -## Finally, if there are sites inside your gateway that you would like to -## connect to, you can list them in the "no_proxy" variable. This will allow -## you to connect to them directly and skip going through the proxy: -## -## setenv no_proxy "www.this,www.that,www.other" -## -## I (jfriedl@omron.co.jp) have little personal experience with proxies -## except what I deal with here at Omron, so if this is not representative -## of your situation, please let me know. -## -## RETURN VALUE -## The value returned to the system by webget is rather screwed up because -## I didn't think about dealing with it until things were already -## complicated. Since there can be more than one URL on the command line, -## it's hard to decide what to return when one times out, another is fetched, -## another doesn't need to be fetched, and a fourth isn't found. -## -## So, here's the current status: -## -## Upon any timeout (via the -timeout arg), webget immediately -## returns 3. End of story. Otherwise.... -## -## If any URL was fetched with a date limit (i.e. via -## '-update/-refresh/-IfNewerThan' and was found to not have changed, -## 2 is returned. Otherwise.... -## -## If any URL was successfully fetched, 0 is returned. Otherwise... -## -## If there were any errors, 1 is returned.
