Hello, I'm using a web2 server with Basic authentication provided by twisted.web2.auth.basic There are cases when PUT requests with attachments from a client time out, as following: 1. When the client issues the first PUT request, without an Authentication header, the server responds with a 401 Unauthorized before receiving all the attachment (I see this in a TCP trace made with ngrep). I want to ask if this is the right behavior, I saw that Apache waits for the entire attachment before replying with 401. 2. The client I used sends the next PUT request right after the attachment, without an \r\n separator, e.g. ...<closing-xml-tag>PUT /resource HTTP/1.1 Host: ... Is this normal ? Sometimes, when the attachment is bigger, some 10KB, the second PUT sent by the client (with the Authentication header present), is not entirely received by the server, which times out as it waits for the entire attachment, with size = ContentLength. I've printed the data received on the TCP socket, in the doRead() method of twisted.internet.tcp.Connection, and I think sometimes in the processing the HTTPChannel or HTTPFactory stops reading the data, it close the connection for reading, or something like that. Did anyone got a similar behavior? Thank you.
