Re: [Simpletest-support] SimpleBrowser hanging due to content-length

[Roy R. <tch...@gm...>]

The bug you posted:
https://bugs.php.net/bug.php?id=51330
Has an answer that says it's related to the server's keep-alive designation. Perhaps a library that simple test browser uses respects keep-alive. 

If you can modify that header, that may solve the timeout.
