Description Philip Withnall 2009-03-23 18:23:16 UTC 
If a large number of g_file_load_contents_async()s (for example) are issued in a short space of time for a HTTP file, the GVFS HTTP backend will happily make all the connections simultaneously, which crashes my router. It doesn't seem to take SoupSession's max-conns or max-conns-per-host properties into account, which it should do; or have its own equivalents.

Test case and Wireshark log coming up.

Test case for number of connections

Test case. If the network traffic is logged, all the requests/connections are made within 100ms. Log coming up.

Whoops, duplicate upload. Ignore the first one.

This should be fixed with the use of a single SoupSession in bug 732090. Thanks.
