Description
I am using your class to implement a queue which will run one job per process and then loop on itself by making a remote non blocking call.
I was facing an issue that was very painful to debug because Apache was simply dropping the request with the following message:
POST /wp-admin/admin-post.php HTTP/1.1" 400 306 "-" "-" "Size of a request header field exceeds server limit.<br />\n<pre>\ncookie\n</pre>/n
I our case we forward cookies from one async call to another. The fact that you serialize the $_COOKIE value that are arrays, https://github.com/techcrunch/wp-async-task/blob/master/wp-async-task.php#L132, results in a header size that keeps increasing:
%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C...
Any reason you added this serialization? Does not seem to be handled natively by WP, right?
Do you think of a serialization that would scale in our case? For now we just ignore non string values, which is sufficient.
Great lib, keep it up!
