Subject: Support for HTTP transfer timeouts based on transfer speed
X-Git-Tag: v0.99.9~79^2~9
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e0004e286c50364f134c951754c34e815489ead0;p=git.git

Support for HTTP transfer timeouts based on transfer speed

Add configuration settings to abort HTTP requests if the transfer rate
drops below a threshold for a specified length of time.  Environment
variables override config file settings.
