I'm testing a workaround to the problem I was having loading the contents of certain remote pages when posting a 'like'.

As my workflow already grabs the page title (so I can check it before posting) I now add this to the post as an additional custom field.

I have then created a stream context with a 15 second timeout:

$opts = array(
  'http'=>array(
    'method'=>'get',
    'timeout'=>15,
  )
);

$context = stream_context_create($opts);

and applied it to the remote page collection:

$doc->loadHTMLFile($meta_url, false, $context);

So, if the attempt at loading the page within WordPress times out a quick check means it will fall back to the new custom field instead.

I'll add this to the 'reply' workflow as well.
