    This is in the documentation for LWP::Simple:
    The user agent created by this module will identify itself as "LWP::Simple/#.##" (where "#.##" is the libwww-perl version number) and will initialize its proxy defaults from the environment (by calling $ua->env_proxy).
    and for LWP::UserEgent:
    $ua->env_proxy
    Load proxy settings from *_proxy environment vari­ables. You might specify proxies like this (sh-syntax):
                 gopher_proxy=http://proxy.my.place/
                 wais_proxy=http://proxy.my.place/
                 no_proxy="localhost,my.domain"
                 export gopher_proxy wais_proxy no_proxy
    
    csh or tcsh users should use the "setenv" command to define these environment variables.

    On systems with case insensitive environment variables there exists a name clash between the CGI environment variables and the "HTTP_PROXY" environment variable normally picked up by env_proxy(). Because of this "HTTP_PROXY" is not honored for CGI scripts. The "CGI_HTTP_PROXY" environment variable can be used instead.

    So you should be able to simply set the appropriate environment variables.

    From the pod of LWP::Simple :

    The user agent created by this module will identify itself as "LWP::Simple/#.##" (where "#.##" is the libwww-perl version number) and will initialize its proxy defaults from the environment (by calling $ua->env_proxy).

    And accordingly looked up in the pod of LWP::UserAgent (emphasis again mine):

    Load proxy settings from *_proxy environment variables. You might specify proxies like this (sh-syntax):
    • gopher_proxy=http://proxy.my.place/
    • wais_proxy=http://proxy.my.place/
    • no_proxy="localhost,my.domain"
    • export gopher_proxy wais_proxy no_proxy
    csh or tcsh users should use the "setenv" command to define these environment variables.
    On systems with case insensitive environment variables there exists a name clash between the CGI environment variables and the "HTTP_PROXY" environment variable normally picked up by env_proxy(). Because of this "HTTP_PROXY" is not honored for CGI scripts. The "CGI_HTTP_PROXY" environment variable can be used instead.

    So just set up the environment accordingly, and LWP::Simple DWYM.

    From the LWP::Simple manpage:
    The user agent created by this module will identify itself as "LWP::Simple/#.##" (where "#.##" is the libwww-perl version number) an +d will initialize its proxy defaults from the environment (by calling $ua->env_proxy).
    I think they mean the HTTP_PROXY environment-variable, so in your script you could set something like:
    $ENV{'HTTP_PROXY'}='http://proxy:3128/';
    before you create the user agent.
