<p class=MsoNormal><span lang=EN-US>Hi, <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
I write a fastcgi server and use nginx to pass request to my server. It works
till now. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
But I find a problem. Nginx always set requestId = 1 when sending fastcgi
record.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
I was a little upset for this, cause according to fastcgi protocol, web server
can send fastcgi records belonging to different request simultaneously, and
requestIds are different and keep unique. I really need this feature,
because requests can be handled simultaneously just over one connetion. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
Can I find a way out?<o:p></o:p></span></p>
