         my $entry = shift;   # entries item in har
         
         # request of the entry item. Note: this is not the HTTP::Request instance
         my $request = $entry->{request};

         return 0 if $request->{url} =~ /\.(?:gif|png|css|js)(?:\?.*)?$/;
         
         # modify post params

             $request->{postData}->{text} =~ s/username=\w+/username=Tom/;
         }
         
         # must return true to request this entry
         return 1;

         # $res is a HTTP::Response intance, decoded
         my ($entry, $res, $entries) = @_;
         
         # you can print or capture something from some response
         if ($entry->{request}->{url} =~ /refreshresume/) {

SUBROUTINES/METHODS

walk_har($ua, $har_file, $before_sub, $after_sub)

Walk through all the entries in the HAR file, and issue each request.

The first two arguments is required. The $ua is a LWP::UserAgent instance, you can do some configuration first, eg: set timeout. $har_file is the HAR file you recorded.

The last two arguments are for hooks. In the before hook you can decide wheather this request shall be sent, you can return false to skip some unnessary request, such as images, css, etc. You can modify the $entry here. Eg: you can change the username and password in the postData to replay twitter requests with another user. The prototype of the before hook is:

sub {
    my ($entry) = @_;
    return 1;
}

The after hook is for people to get some information from the response. Eg: get some link to download and push them into @$entries. It is prototype is :

sub {
    my ($entry, $res, $entries) = @_;
}

The $entry is the item in the entries array in the HAR file ( log -> entries ). The $res is a decoded HTTP::Response instance.
