I show it here, and please forgive me I’m not familiar with the code and compiler language, I will describe the question as detailed as possible. When I use the nginx as a Reverse Proxy for google site, Searching the “Google Image” will display different effects with different version of nginx. Previously, I used the nginx-1.4.7 stable version, the picture from the google image could buffer very quickly in one second. But when I update the nginx to the nginx-1.7.8, some pictures from google always show as a Blank frame, or it will spend a long time to display the picture. For example, during using the nginx-1.7.8, if one page could show 12 pics of picture, actually, I only get the 10 of the 12 pics, another 2 pics is displayed as the Blank Picture (the reference picture is attached here). OR, if I want to see the following picture, the new version nginx could show the result immediately, after about half minute or 1 minute, it could display the picture as usual (or as the effect from nginx-1.4.7). However, when I use the nginx-1.4.7/1.4.6, the picture could be displayed completely through any away. For solving this problem, I have tried several version of the nginx in the same envirnoment. Unfortunately, except the nginx-1.4.7/1.4.6, the lasted versions of Nginx always appear the problem described above, including the nginx-1.5.12 which is released in the same time as nginx-1.4.7. I have set the nignx with the following modules : ---- ./configure --prefix=/opt/nginx --with-pcre=../pcre-8.36 --with-openssl=../openssl-1.0.1j --with-zlib=../zlib-1.2.8 --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_spdy_module --with-ipv6 ---- And this is the mian line from nginx.conf: ---- user www-data; worker_processes 1; pid /run/nginx.pid; daemon on; events { worker_connections 5120; } http { sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; variables_hash_bucket_size 128; variables_hash_max_size 1024; include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; gzip on; gzip_disable ""msie6""; gzip_vary on; gzip_proxied any; gzip_comp_level 6; gzip_min_length 1k; gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; proxy_buffers 8 64k; ---- The following is the captured image about the trial, The different nginx version I tried: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9EMlVCYkxRVk1tU1E/view?usp=sharing)]] Actually, I've tested several version. The display effect from nginx-1.4.7: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9ENUsxT3lIRjZhSFk/view?usp=sharing)]] The nginx-1.4.7 could work well, we could see the all pictures. The display effect from nginx-1.5.12: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9EelBLenY1V2VoUm8/view?usp=sharing)]] But for nginx-1.5.12(the time released is same as nginx-1.4.7), some picture couldn't be showed out. The display effect from nginx-1.5.12: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9EVDkyRlNHVXdnUW8/view?usp=sharing)]] Normally, after 1 or a half minute later, the picture behind could be loaded. The display effect from nginx-1.7.8: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9EVDlERGtOa2tOVHc/view?usp=sharing)]] The nginx-1.7.8 also have this problem. The display effect from nginx-1.7.9: [[Image(https://drive.google.com/file/d/0B4uKV-AeSn9EMjZpTEZ1MEkzeGs/view?usp=sharing)]] And the latest one's effect for google image. (All the nginx version is tested in the same compiler environment.)
