Hello, I’m using Nginx as a reverse proxy and I’m seeing 500 errors anytime the proxy\_cookie\_domain option feature is used. I’m trying to change the domain in the “Set-Cookie” header. The response header shows the replaced domain properly in the “Set-Cookie” header, however, it is a 500 Error response and does not output the page content. Is there any way to find the cause of this error? I tried using both strace and the debug log, but could not find any cause. Here is a snippet of the debug log 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy header: “User-Agent: curl/7.15.5 (i686-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy header: “Accept: _/_” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy header: "GET /test HTTP/1.0 Host: [server.com](http://server.com) Connection: close User-Agent: curl/7.15.5 (i686-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5 Accept: _/_ " 2012/05/18 13:16:10 [debug] 31932#0: \*1 http cleanup add: 09030628 2012/05/18 13:16:10 [debug] 31932#0: \*1 get rr peer, try: 1 2012/05/18 13:16:10 [debug] 31932#0: \*1 socket 12 2012/05/18 13:16:10 [debug] 31932#0: \*1 epoll add connection: fd:12 ev:80000005 2012/05/18 13:16:10 [debug] 31932#0: \*1 connect to 194.71.107.15:80, fd:12 #2 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream connect: -2 2012/05/18 13:16:10 [debug] 31932#0: \*1 posix\_memalign: 0902A140:128 @16 2012/05/18 13:16:10 [debug] 31932#0: \*1 event timer add: 12: 60000:1626601550 2012/05/18 13:16:10 [debug] 31932#0: \*1 http finalize request: -4, “/test” a:1, c:2 2012/05/18 13:16:10 [debug] 31932#0: \*1 http request count:2 blk:0 2012/05/18 13:16:10 [debug] 31932#0: \*1 http run request: “/test” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream check client, write event:1, “/test” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream recv(): -1 (11: Resource temporarily unavailable) 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream request: “/test” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream send request handler 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream send request 2012/05/18 13:16:10 [debug] 31932#0: \*1 chain writer buf fl:1 s:278 2012/05/18 13:16:10 [debug] 31932#0: \*1 chain writer in: 09030644 2012/05/18 13:16:10 [debug] 31932#0: \*1 writev: 278 2012/05/18 13:16:10 [debug] 31932#0: \*1 chain writer out: 00000000 2012/05/18 13:16:10 [debug] 31932#0: \*1 event timer del: 12: 1626601550 2012/05/18 13:16:10 [debug] 31932#0: \*1 event timer add: 12: 60000:1626601723 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream request: “/test” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http upstream process header 2012/05/18 13:16:10 [debug] 31932#0: \*1 malloc: 09030A88:4096 2012/05/18 13:16:10 [debug] 31932#0: \*1 recv: fd:12 2920 of 3979 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy status 200 “200 OK” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy header: “X-Powered-By: PHP/5.4.1” 2012/05/18 13:16:10 [debug] 31932#0: \*1 http proxy header: “Set-Cookie: PHPSESSID=055997276de6833c13c98c8707581925;
