A lot of specialists argue that home loans aid people to live the way they want, because they are able to feel free to buy needed things. Furthermore, banks offer bank loan for different persons.

@Fitzgerald,
Yes. The value of content_type_len is usually the same as content_type.len, but in some case, i.e. when there’s charset setting with the Content-Type HTTP header, e.g. given header “Content-Type: text/html; charset=UTF-8″, content_type_len (23) is less than content_type.len (38).

When setting the content type header; this looks a bit odd to me:
r->headers_out.content_type_len = sizeof(”text/html”) - 1;
r->headers_out.content_type.len = sizeof(”text/html”) - 1;

is this OK?

看了Velocity 2010 Highlights，科幻一把：种一亩地的效益比不上种十亩地，10亩比不上1000亩…………………………………………最后，世界上只有几个巨头农场主——嗯，云计算的成熟阶段。那一天快点到吧！

Hey Rogério, this is feasible, I think. Please give a look at agentzh’s ngx_echo module implementation which might give you a hint (http://github.com/agentzh/echo-nginx-module/), especially the “echo_sleep” and “echo_flush” directives.

Joshua, yes, I am looking for a comet implementation, BUT I need it to be streaming, not long polling
Do you know if this is possible to achieve, and how? Updating the output chain in chunks, gradually, as they become available by publishing new messages?

Regards,
Rogério Schneider

@Rogério:
Hi, I guess you are looking for something similar to Leo Ponomarev’s push module (http://pushmodule.slact.net/)?

Joshua, thanks for the amazing content on Nginx internals.

Now I have a question:
- How could I write a module that returns a chunked encoding response without cliosing the users connection, ever?
I would like to respond in little chunks to the user, and, as the time passes, updating this connection with new chunks of data. The connection would not be closed, ever.

Thanks again.
