  • How do you configure apache2 to serve SVG files?

    - by Neil
    I've added these lines to /etc/apache2/apache2.conf: AddEncoding gzip .svgz AddType image/svg+xml .svg AddType image/svg+xml .svgz But SVG files still appear as broken images on my html page served by Apache. I made sure I restarted the webserver, browser and cleared the cache as well. How do you get SVG files to work with Apache2?

  • HTTP Compression Proxy

    - by Praveen
    I'm looking for a HTTP compression proxy. Basically, I need a proxy to compress images and text to be transferred over a slow internet connection when accessing the web. To put it into a diagram CLIENT ---/fast local network/--- HTTP COMPRESSION PROXY ---/slow internet connection/--- WEB (e.g. Facebook, Wiki, Google) I will be using Squid for caching but from what i've it does not support HTTP compresion (gzip, deflate)

  • Configuration issue with HttpRealipModule (CloudFlare) in nginx configuration file

    - by Tyrx
    I've been attempting to use HttpRealipModule with the CloudFlare IP range in my main nginx configuration file but upon restarting nginx I'll just get a standard `"configuration file /etc/nginx/nginx.conf test failed" and my site will go down. This is what I've been attempting to do with my nginx.conf; user www-data; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { # Basic Settings set_real_ip_from 204.93.240.0/24; set_real_ip_from 204.93.177.0/24; set_real_ip_from 199.27.128.0/21; set_real_ip_from 173.245.48.0/20; set_real_ip_from 103.22.200.0/22; set_real_ip_from 141.101.64.0/18; set_real_ip_from 108.162.192.0/18; set_real_ip_from 190.93.240.0/20; set_real_ip_from 188.114.96.0/20; set_real_ip_from 2400:cb00::/32; set_real_ip_from 2606:4700::/32; set_real_ip_from 2803:f800::/32; real_ip_header CF-Connecting-IP; client_max_body_size 50m; client_header_timeout 5; keepalive_timeout 5; port_in_redirect off; sendfile on; server_tokens off; server_name_in_redirect off; tcp_nopush on; tcp_nodelay on; types_hash_max_size 2048; # MIME include /etc/nginx/mime.types; default_type application/octet-stream; # Logging Settings access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log warn; # Gzip Settings gzip on; gzip_disable "msie6"; gzip_min_length 1400; gzip_types text/plain text/css text/javascript text/xml application/x-javascript application/xml application/xml+rss; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } What's wrong with that configuration file?

  • Secret, unlogged, transparent, case-sensitive proxy in IIS6?

    - by Ian Boyd
    Does IIS have a secret, unlogged, transparent, case-sensitive proxy built into it? A file exists on the web-server: GET http://www.stackoverflow.com/javascript/ModifyQuoteArea.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:20:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... Problem is that a changes made to the file will not get served, the old (i.e. February of last year) version keeps getting served: HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:23:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... The same old file gets served, even though we've: renamed the file deleted the file restarted IIS The request for this file does not appear in the IIS logs (e.g. C:\WINNT\System32\LogFiles\W3SVC7\) And this only happens from the outside (i.e. the internet). If you issue the request locally on the server, then you will: - get the current file (file there) - 404 (file renamed) - 404 (file deleted) But if i change the case of the requested resource, i.e.: GET http://www.stackoverflow.com/javascript/MoDiFyQuOtEArEa.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com Note: MoDiFyQuOtEArEa.js verses ModifyQuoteArea.js Then i do get the proper file (or get the 404 as i expect if the file is renamed or deleted). But any subsequent changes to the file will not show up until i change the case of the file i'm asking for. Checking the IIS logs all indicate that the (internet) requests are all coming the correct client on the internet (i.e. not from some intermediate proxy). Since the file doesn't exist on the hard drive anymore, i conclude that there is a proxy. The requests serviced from this proxy are not logged in the IIS logs. The requests for new files are logged, and from the client IP, not a proxy IP. The proxy is case sensitivie. This does not sound like something Microsoft, or IIS, would do: - a transparent proxy - case-sensitivie - unlogged - surviving restarts of IIS - surviving in a cache for hours i can't believe that our customer's IIS is doing these things. i'm assuming there is some other transparent proxy in front of IIS. Or, does IIS have a transparent, unlogged, case-sensitive, memory based, proxy, that caches content for at least 7 hours? (Come Monday morning, IIS is serving the correct file, unlogged).

  • Google Chrome shows garbage text instead of web page

    - by Sarfraz Ahmed
    On some websites, I receive garbage text instead of web page itself. I have noticed that this only happens for pages that are served with Content-Encoding set to GZIP or chunked headers, see the image please: I am using latest version 22.0.1229.94 of Chrome with Windows 7 Ultimaate. The encoding of browser is set to UTF-8. (I also tried changing encoding to Western, etc but same result) Can anyone suggest a solution to this? Thanks

  • NGiNX performance degrades over time.

    - by Rylea Stark
    So here's the situation, I run a small cluster, Dedicated box for MySQL, and a dedicated PHP-FPM/NGINX box, Nginx talks to php-fpm via socket, As far as i can tell the problem does not lie in php-fpm, it lies somewhere in my configuration. What happens, is the site loads instant for a few moments after starting and slowly starts to degrade to load times of greater than 2 seconds, eventually taking 12 seconds to complete a load, PHP is configured to close a child after 175 requests, and spawn 20 at start and have a max of 60. Not really sure where the bottle neck is, most of my code is optimized and works flawlessly, but these issues with nginx will most likely force me to switch back over to Apache, And I really dont want to do that, NGINX.conf configuration below. user www-data; worker_processes 4; worker_cpu_affinity 0001 0010 0100 1000; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 512; multi_accept on; use epoll; } http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; resolver_timeout 5s; satisfy all; ## Size Limits limit_zone brainbug $binary_remote_addr 5m; client_body_buffer_size 8k; client_header_buffer_size 75M; client_max_body_size 1k; large_client_header_buffers 2 1k; ## Timeouts client_body_timeout 60; client_header_timeout 60; keepalive_timeout 60; send_timeout 60; ## General Options ignore_invalid_headers on; recursive_error_pages on; sendfile on; server_name_in_redirect off; server_tokens off; ## TCP options tcp_nodelay on; #tcp_nopush on; output_buffers 128 512k; gzip on; gzip_http_version 1.0; gzip_comp_level 7; gzip_proxied any; gzip_min_length 0; gzip_buffers 32 32k; gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript image/jpeg image/png image/gif; ## Disable GZIP for MSIE 1-6 gzip_disable "MSIE [1-6].(?!.*SV1)"; ## Set a vary header so downstream proxies don't send cached gzipped content to IE6 gzip_vary on; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; }

  • MySQL Backup - incremental

    - by Tiffany Walker
    I know that you can use mysqldump. I am currently dumping the following way: ${MYSQLDUMP} --single-transaction -u ${MUSER} -h ${MHOST} -p${MPASS} $db | ${GZIP} -9 > $FILE From my understanding this locks the database and prevents any type of use of the database and can even lock up websites. Is there a better way to maybe do daily/hourly backups of the MySQL database should the database be in the 100mbs and even 1gbs in size?

  • How to copy directory from one Linux server to another with a minimum in-between period?

    - by yegor256
    I have a rather big directory on one server (over 4000 files), which I'd like to copy to another server (which contains a previous version of this directory). rsync is the first option, but it will put the destination folder into waiting status for a rather long period of time (more than a minute). I'd like to do it a bit differently: gzip the source folder scp the archive to the destination server gunzip the file there delete the archive at the source and the destination What is the best way to accomplish all this?

  • Single line command/script to archive a certain amount of folders

    - by EarthMind
    I'm looking for a single line command or a script that archives 5 folders into .tar files (no gzip/bzip needed) in a certain directory and deletes the folders after a successful compression. It has to use the original folder name as file name for the archive too. So far I've used the current command, which only does one directory per time: tar -c directory > directory.tar && rm -rf directory Thanks in advance.

  • Safe to disable compile options for Nginx (when used only as reverse proxy/cache)

    - by Alex
    I have read that I can do this to make a smaller footprint Nginx when used as static content cache/reverse proxy: --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module What other options are safe to disable? SSI, FastCGI? Others? The only requirements for the reverse proxy is to be able to do https and gzip compression. Will disabling all the module really help with footprint and/or performance?

  • Binary diff/patch for large files on linux?

    - by thejh
    I've got two partition images (A and B) and want to use them to create a patch that I can apply on A on another computer in order to get the new B image without flooding the network. I have the following requirements: works on linux can create diffs can use diffs to patch files can handle binary files can handle large files (a few hundred GB should work) no user interaction required (just a console application) ideally, should be able to read from/write to pipes (so that I can pipe into it from a gzip-compressed file and write to one) Does something like that exist?

  • PHP File Serving Script: Unreliable Downloads?

    - by JGB146
    This post started as a question on ServerFault ( http://serverfault.com/questions/131156/user-receiving-partial-downloads ) but I determined that our php script was the culprit. So I'm issuing an updated question here about what I believe is the actual issue. I am using a php script to verify permissions and then serve up a file for users of my website to download. Most of the time, this works, but recently one user has been seeing problems with larger downloads. He is only getting ~80% of downloads for files that are 100MB in size. Also, all downloads from this script fail to report a filesize. Further, tests revealed that the same user COULD reliably download each of the failed files if given a direct link (at which point the filesize is reported). Here's the relevant snippet of code that we are using to serve the file: header("Content-type:$contenttype"); $len = filesize($filename); header("Content-Length: $len"); header("Content-Disposition: attachment; filename=".$title.".".$ext); readfile($filename); Note that $contenttype, $filename, $title, and $ext are all set correctly before we get here. These have been triple-checked. None of them are the problem. Also, $len does provide the correct filesize. While researching this issue, I came across this post: http://stackoverflow.com/questions/1334471/content-length-header-always-zero It seems that I am encountering the same issue. When I use the script, I get chunked encoding on the file and no size is set for content-length. I'm hypothesizing that something is going wrong on the large downloads, leading him to get a zero-length chunk before the end of the file. Here's what the headers look like for a direct request: http://www.grinderschool.com/videos/zfff5061b65ae00e8b21/KillsAids021.wmv GET /videos/zfff5061b65ae00e8b21/KillsAids021.wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://www.grinderschool.com/phpBB3/viewtopic.php?f=14&p=29468 Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 Pragma: no-cache Cache-Control: no-cache HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:57:41 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 Last-Modified: Sun, 04 Apr 2010 12:51:06 GMT Etag: "eb42d6-7d9b843-48368aa6dc280" Accept-Ranges: bytes Content-Length: 131708995 Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Content-Type: video/x-ms-wmv And here's what they look like for the request answered by my script: http://www.grinderschool.com/download_video_test.php?t=KillsAids021&format=wmv GET /download_video_test.php?t=KillsAids021&format=wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:58:02 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 X-Powered-By: PHP/5.2.11 Content-Disposition: attachment; filename=KillsAids021.wmv Vary: Accept-Encoding Content-Encoding: gzip Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: video/x-ms-wmv So the question is...what can I do to make downloads from the script work properly? Again, for 99% of users, it works as is (though I find it annoying now that no filesize is reported and thus that no time estimate can be computed about the download).
