Subject: http-proxy: deal with EAGAIN
X-Git-Tag: curl-7_55_0~179
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=12ccaed2a53c07edb12f5b4e944d3a78e6a6fa0c;p=thirdparty%2Fcurl.git

http-proxy: deal with EAGAIN

... the previous code would reset the header length wrongly (since
5113ad0424). This makes test 1060 reliable again.

Also: make sws send even smaller chunks of data to increase the
likeliness of this happening.
