Losing 'post' requests sent to Pylons paster server
- by Philip McDermott
I'm sending post requests to a Pylons server (served by paster serve), and if I send them with any frequency many don't arrive at the server. One at a time is ok, but if I fire off a few (or more) within seconds, only a small number get dealt with. If I send with no post data, or with get, it works fine, but putting just one character of data in the post fields causes massive losses.
For example, sending 200, 2 will come back. Sending 100 more slowly, 10 will come back.
I'm making the requests form inside a Qt application. Tis will work ok (no data):
QString postFields = ""
QNetworkRequest
request(QUrl("http://server.com/endpoint"));
QNetworkReply *reply =
networkAccessManager-post(request,
postFields.toAscii());
And this will result in only a fraction of the requests being dealt with:
QString postFields = ""
QNetworkRequest
request(QUrl("http://server.com/endpoint"));
QNetworkReply *reply =
networkAccessManager-post(request,
postFields.toAscii());
I've played around with turning on use_threadpool, and other options (threadpool_workers, threadpool_max_requests = 300), of which some combinations can alter the results slightly (best case 10 responses in 200).
If I send similar requests to other (non paster) servers, the replies come back ok, so I'm almost certain its'a paster serve config issue.
Any help or advice greatly appreciated.
Thanks
Philip
