Stream module logging questions

Hello, 1. How can I log the IP and (especially) the port used by nginx (proxy) to connect to upstream when stream module is used? 2. Can I somehow get a log entry also/instead at stream connection setup time, not only after it ends? 3. I think that $tcpinfo_* aren't supported in stream. Is

Re: fsync()-in webdav PUT

This discussion is interesting, educational, and thought provoking. Web architects only learn “the right way” by first doing things “the wrong way” and seeing what happens. Attila and Valery asked questions that sound logical, and I think there's value in exploring what would happen if their

Valery, may you please suggest how you came to the conclusion that “fsync simply instructs OS to ensure consistency of a file"? As far as understand simply instructing OS staff come at no cost, right? > Without fsyncing file's data and metadata a client will receive a positive > reply

Re: fsync()-in webdav PUT

Not waiting for fsync to complete makes calling fsync pointless, waiting for fsync is blocking, thread based or otherwise. The only midway solution is to implement fsync as a cgi, ea. a none-blocking (background)fc call in combination with an OS resource lock. Posted at Nginx Forum:

ngx_stream_auth_request?

Re: proxy_pass and concurrent connections

Hello, thanks for your answer. The documentation is explicit when an upstream server is used with proxy_pass, but it says nothing, when proxy_pass is used with an URL. Being explicit somewhere and stating nothing on the same manner in an alternative scenario leaves space for

Re: fsync()-in webdav PUT

It's completely clear why someone would need to flush file's data and metadata upon a WebDAV PUT operation. That is because many architectures expect a PUT operation to be completely settled before a reply is returned. Without fsyncing file's data and metadata a client will receive a positive

Client certificates and check for DN?

Hi, it seems most examples, even for apache, seem to assume that the client certificates are issued by your own CA. In this case, you just need to check if your certificates were issued by this CA - and if they're not, it's game over. However, I may have a case where the CA is a public CA

Re: fsync()-in webdav PUT

While it’s not clear why one may need to flush the data on each http operation, I can imagine to what performance degradation that may lead of. if it’s not a some kind of funny clustering among nodes, I wouldn't care much where actual data is, RAM still should be much faster, than disk I/O.
