Sergio is right: WebKitGTK+ enables the network-process when using WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES [1] because it is not be safe to access the on-disk cache from multiple processes at the same time (accessing cookie jars has the same problem, too). With the network-process enabled, web-processes do not directly access the network or the on-disk cache: instead they ask the network-process to fetch resources for them. This way only one process is accessing the caches on-disk (the network-process). I hope this clarifies why the network-process is needed — and why it is not a problem for the on-disk caches to enable it, but an actual need. Cheers, -Adrian
