  • Lightweight HTTP application/server for static content

    - by PartlyCloudy
    Hi, I am in need of a scalable and performant HTTP application/server that will be used for static file serving/uploading. So I only need support for GET and PUT operations. However, there are a few extra features that I need: Custom authentication: I need to check credentials against a database for each request. Thus I must be able to integrate propietary database interaction. Support for signed access keys: The access to resources via PUT should be signed using a key like http://uri/?key=foo The key then contains information about the request like md5(user + path + secret) which allows me to block unwanted requests. The application/server should allow me to check for this. Performance: I'd like to avoid piping content as much as possible. Otherwise the whole application could be implemented in Perl/etc. in a few lines as CGI. Perlbal (in webserver mode) looks nice, however the single-threaded model does not fit with my database lookup and it does also not support query strings. Lighttp/Nginx/… have some modules for these tasks, however it is not feasible putting everything together without ending up writing own extensions/modules. So how would you solve this? Are there other leightweight webservers available for this? Should I implement an application inside of a webserver (i.e. CGI). How can I avoid/speed up piping content between the webserver and my application. Thanks in advance!

  • Serving web application without Lighttpd/Apache

    - by Shyam
    Hi, As Rails applications default run on port 3000, would it be possible to start the application on port 80? Is it really required to have a fastcgi/mod_proxy enabled web server in front? My users won't be more than three at a time. If so, how would I be able to do so? Thanks!

  • Crontab - stop sending mail, special case ||

    - by 2ge
    Hi all, I need to put into my crontab small command, which is checking, if lighttpd web server is running, for some reason it hangups sometimes. So I got there: * * * * * root /bin/pgrep lighttpd || /usr/local/etc/rc.d/lighttpd restart >/dev/null 2>&1 problem is, this send me mail every minute, in the mail is number of PID of lighttpd, which is running. For other crontab job, redirection work, so I assume, when is there "||", it makes problem. maybe there should be better to rewrite crontab job, so it uses exit status of pgrep, so I can avoid "||". I am using FreeBSD. Thanks for any help, for now I disabled this job

  • Ajax long polling (comet) + php on lighttpd v1.4.22 multiple instances problem.

    - by fibonacci
    Hi, I am new to this site, so I really hope I will provide all the necessary information regarding my question. I've been trying to create a "new message arrived notification" using long polling. Currently I am initiating the polling request by window.onLoad event of each page in my site. On the server side I have an infinite loop: while(1){ if(NewMessageArrived($current_user))break; sleep(10); } echo $newMessageCount; On the client side I have the following (simplified) ajax functions: poll_new_messages(){ xmlhttp=GetXmlHttpObject(); //... xmlhttp.onreadystatechange=got_new_message_count; //... xmlhttp.send(); } got_new_message_count(){ if (xmlhttp.readyState==4){ updateMessageCount(xmlhttp.responseText); //... poll_new_messages(); } } The problem is that with each page load, the above loop starts again. The result is multiple infinite loops for each user that eventually make my server hang. *The NewMessageArived() function queries MySQL DB for new unread messages. *At the beginning of the php script I run start_session() in order to obtain the $current_user value. I am currently the only user of this site so it is easy for me to debug this behavior by writing time() to a file inside this loop. What I see is that the file is being written more often than once in 10 seconds, but it starts only when I go from page to page. Please let me know if any additional information might help. Thank you.

  • Configure FastCGI for Python

    - by Rob
    I have nginx running on a VM and I want to run a Trac site. I need to run a python FastCGI server, but I cannot tell which is the server to use. I have found the following: <a href="http://redmine.lighttpd.net/projects/spawn-fcgi">Lighttpd spawn-fcgi</a> But this seems to require that you compile lighttpd just to get the fcgi server, which is weird. <a href="http://svn.saddi.com/py-lib/trunk/fcgi.py">fcgi.py</a> But this one seems to be depreciated. At the very least it is poorly documented. <a href="http://trac.saddi.com/flup">flup</a> This one comes with dependencies on ubuntu (python-cheetah{a} python-mysqldb{a} python-webpy{a}) that seem unnecessary. Also poorly documented. Are their any recent guides for setting this up. Trac's own FastCGI setup page seems to miss some steps.

  • Squid on windows loadbalancing only to one server

    - by Martin L.
    After thousands of googles and trying days i cant get the load balancer/failover in squid on windows to work. Iam using squid 2.7. My webservers are 2 single NIC lighttpd and one dual nic lighttpd. server1 in this example is running squid on port 80 and lighttpd on port 8080 (just to test) Requirements: All 3 webservers running lighttpd should be balanced two option for load balancing: Best would be if server1 is busy server2 takes over, if server2 is busy server3 takes over, etc.. Round robin style evenly distributed load. Eg server1 takes first call, server2 second etc.. All requests should be treated the same way (no url rewriting or so on) Sent host headers have to be redirected to every server as http host header, speaking of "server1", "server1.company.internal" and "10.211.1.1". My approach: acl all src all acl manager proto cache_object http_port 80 accel defaultsite=server1.company.internal vhost #reverse proxy entries cache_peer 10.211.2.1 parent 8080 0 no-query originserver round-robin login=PASS name=server1_nic1 cache_peer 10.211.1.2 parent 80 0 no-query originserver round-robin login=PASS name=server2_nic1 cache_peer 10.211.2.3 parent 8080 0 no-query originserver round-robin login=PASS name=server3_nic1 cache_peer 10.211.2.4 parent 8080 0 no-query originserver round-robin login=PASS name=server3_nic2 #decl of names of squid host acl registered_name_hostdomain dstdomain server1.company.internal acl registered_name_host dstdomain server1 #ip of squid host acl registered_name_ip dstdomain 10.211.2.1 # access: redirects the correct squid hostname http_access allow registered_name_hostdomain http_access allow registered_name_host http_access allow registered_name_ip http_access deny all cache_peer_access server1_nic1 allow registered_name_hostdomain cache_peer_access server1_nic1 allow registered_name_host cache_peer_access server1_nic1 allow registered_name_ip cache_peer_access server2_nic1 allow registered_name_hostdomain cache_peer_access server2_nic1 allow registered_name_host cache_peer_access server2_nic1 allow registered_name_ip cache_peer_access server3_nic1 allow registered_name_hostdomain cache_peer_access server3_nic1 allow registered_name_host cache_peer_access server3_nic1 allow registered_name_ip cache_peer_access server3_nic2 allow registered_name_hostdomain cache_peer_access server3_nic2 allow registered_name_host cache_peer_access server3_nic2 allow registered_name_ip cache_peer_access server1_nic1 deny all cache_peer_access server2_nic1 deny all cache_peer_access server3_nic1 deny all cache_peer_access server3_nic2 deny all never_direct allow all Problems: Load balancer does not load balance other than to first server. Only if the first server is killed in any way the second will take over. I have seen the others working at some point, but definitely not as the intended load balancing described above. If the cache_peer_access is not defined sometimes the wrong hostname is sent to the backend webserver and this always depends on the defaultsite= parameter. Probably because the host header on the request to squid is not set and its replaced by defaultsite. Leaving out defaultsite didnt solve the problem. The only workaround i found for this is the current approach with cache_peer_access. Questions: Does the cache_peer_access influence the round-robin? Is there a better workaround to pass the host header to the backed webservers? Which parameters do increase the speed of load balancing or does anyone have a better approach? -Martin

  • h264 inside FLV container vs. MP4 container?

    - by Gotys
    I am developing a tube site, and currently having issues with h264 format . By looking at youtube, I noticed they are putting their hi-def videos into mp4 container, so logically I did the same. Next, I installed mod_h264_streaming for lighttpd to make streaming and timeline-scrubbing work. Problem is, that large files (500mb+ at somewhat high resolution) take for EVER to even start buffering ( I read the flowplayer or other flash players need to download metadata first) . I moved the xmov atom to the front of the file with MP4Box (i tried qt-quickstart too) , and the problem didn't go away. Next I read online I need to interleave audio tracks, so I did that too. No change in slowness. So I tried putting the same exact h264 movie into an FLV container, and the playback buffering starts almost instantly - no slowness. So what am I missing here? Why would I choose MP4 container with mod_264_streaming module , which seems super-slow over a regular FLV container with lighttpd's built-in mod_flv_streaming ? Obviously many websites pick mp4 container , but I fail to understand why ? And as a side question - I tried using HTML5's VIDEO tag to try the same h264 MP4 movie, and the scrubbing is LIGHTING FAST! I looked into lighttpd's log file, and i noticed taht Flash Players append video.mp4?start=234 each time timeline is scrubbed, wheres HTML5's video tag does no such thing . Is this some sort of limitations of Flash ? Why Can't flash streaming be same fast as HTML5 streaming? Thanks to ALL who can help. I very much appreciate this community.

  • User Permissions: Daemon and User

    - by Eddie Parker
    Hello: I often run into this issue on Linux, and I'd love to know the proper way of solving it. Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver. Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy. At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'. Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me. Is there an easier way of doing this? Have I overlooked something? Cheers, -e-

  • eAccelerator ignore my new setting?

    - by Mwebe Nkrumah
    Hi, Im using eAccelerator 0.9.5.2, CentOS 5.3, lighttpd 1.4.22 But because eAccelerator is cached in RAM, I needs too much RAM. So Im trying to cache in hard disk. (my website is not generate money, so Im thinking about cheaper solution) So, I modify /etc/php.d/eaccelerator.ini with below codes: extension="eaccelerator.so" eaccelerator.shm_size="12" eaccelerator.cache_dir="/var/cache/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="0" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="20M" eaccelerator.shm_ttl="1800" eaccelerator.shm_prune_period="0" eaccelerator.shm_only="0" eaccelerator.compress="0" eaccelerator.compress_level="9" eaccelerator.keys="disk_only" eaccelerator.sessions="disk_only" eaccelerator.content="disk_only" So, the output of phpinfo() as below: http://img175.imageshack.us/img175/1104/screenshggot.png But after using "disk_only" in eAccelerator and restart lighttpd & php-cgi using killall, my RAM usage is still high for php-cgi. Reboot the server also not works. The data is created in cache directory, but RAM usage is still high.

  • Socket read() hangs for a while when there is no data to read.

    - by janesconference
    Hi' I'm writing a simple http port forwarder. I read data from port 80, and pass the data to my lighttpd server, on port 8080. As long as I write() data on the socket on port 8080 (forwarding the request) there's no problem, but when I read() data from that socket (forwarding the response), the last read() hangs a lot (about 1 or 2 seconds) before realizing there's no more data and returning 0. I tried to set the socket to non-blocking, but this doesn't work, as sometimes it returns EWOULDBLOCKING even if there's some data left (lighttpd + cgi can be quite slow). I tried to set a timeout with select(), but, as above, a slow cgi could timeout the socket when there's actually some data to transmit. How would you do?

  • Criteria for selecting software for embedded device

    - by Suresh Kumar
    We are currently evaluating Web servers for an embedded device. We have laid down the evaluation criteria for things like HTTP version, Security, Compression etc. On the embeddable side, we have identified the following criteria: Memory footprint Memory management (support for plugging in a custom memory manager) CPU usage Thread usage (support for thread pool) Portability What I want inputs on is: Are there any other criteria that an embeddable software should meet? What exactly does it mean when someone says that a software is designed for embeddable use? We currently have zeroed in on two Web servers: AppWeb Lighttpd (lighty) Feature wise, both the above Web servers seem to be on par. However, it is claimed that AppWeb is designed for embedded use while Lighttpd is not. To choose between the above two Web servers, what criteria should I be looking at?

  • Handling XMLHttpRequest to call external application

    - by Ian
    I need a simple way to use XMLHttpRequest as a way for a web client to access applications in an embedded device. I'm getting confused trying to figure out how to make something thin and light that handles the XMLHttpRequests coming to the web server and can translate those to application calls. The situation: The web client using Ajax (ExtJS specifically) needs to send and receive asynchronously to an existing embedded application. This isn't just to have a thick client/thin server, the client needs to run background checking on the application status. The application can expose a socket interface, with a known set of commands, events, and configuration values. Configuration could probably be transmitted as XML since it comes from a SQLite database. In between the client and app is a lighttpd web server running something that somehow handles the translation. This something is the problem. What I think I want: Lighttpd can use FastCGI to route all XMLHttpRequest to an external process. This process will understand HTML/XML, and translate between that and the application's language. It will have custom logic to simulate pushing notifications to the client (receive XMLHttpRequest, don't respond until the next notification is available). C/C++. I'd really like to avoid installing Java/PHP/Perl on an embedded device. So I'll need more low level understanding. How do I do this? Are there good C++ libraries for interpreting the CGI headers and HTML so that I don't have to do any syntax processing, I can just deal with the request/response contents? Are there any good references to exactly what goes on, server side, when handling the XMLHttpRequest and CGI interfaces? Is there any package that does most of this job already, or will I have to build the non-HTTP/CGI stuff from scratch? Thanks for any help! I am really having trouble learning about the server side of these technologies.

  • Why Illegal cookies are send by Browser and received by web servers (rfc 2109, 2965)?

    - by Artyom
    Hello, According to RFC 2109, 2965 cookie's value can be either HTTP token or quoted string, and token can't include non-ASCII characters. Cookie's RFC 2109 and RFC2965 HTTP's RFC 2068 token definition: http://tools.ietf.org/html/rfc2068#page-16 However I had found that Firefox browser (3.0.6) sends cookies with utf-8 string as-is and three web servers I tested (apache2, lighttpd, nginx) pass this string as-is to the application. For example, raw request from browser: $ nc -l -p 8080 GET /hello HTTP/1.1 Host: localhost:8080 User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.9) Gecko/2009050519 Firefox/2.0.0.13 (Debian-3.0.6-1) 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: windows-1255,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: wikipp=1234; wikipp_username=??????

  • Trying to write up a C daemon, but don't know enough C to continue

    - by JamesM-SiteGen
    Okay, so I want this daemon to run in the background with little to no interaction. I plan to have it work with Apache, lighttpd, etc to send the session & request information to allow C to generate a website from an object DB, saving will have to be an option so, you can start the daemon with an existing DB but will not save to it unless you login to the admin area and enable, and restart the daemon. Summary of the daemon: Load a database from file. Have a function to restart the daemon. Allow Apache, lighttpd, etc to get necessary data about the request and session. A varible to allow the database to be saved to the file, otherwise it will only be stored in ram. If it is set to save back to the file, then only have neccessary data in ram. Use sql-light for the database file. Build a webpage from some template files. $(myVar) for getting variables. Get templates from a directory. ./templates/01-test/{index.html,template.css,template.js} Live version of the code and more information: http://typewith.me/YbGB1h1g1p Also I am working on a website CMS in php, but I am tring to switch to C as it is faster than php. ( php is quite fast, but the fact that making a few mySQL requests for every webpage is quite unefficent and I'm sure that it can be far better, so an object that we can recall data from in C would have to be faster ) P.S I am using Arch-Linux not MS-Windows, with the package group base-devel for the common developer tools such as make and makepgk. Edit: Oupps, forgot the question ;) Okay, so the question is, how can I turn this basic C daemon into a base to what I am attempting to do here?

  • PHP-CGI slowly gains memory despite lack of requests.

  • Tomcat memory usage

    - by Adrian Mester
    I'm running tomcat on a ubuntu 10.4 VPS with 512MB of RAM (1024 burstable). I'm using it for development, so performance isn't an issue, but memory is. Tomcat is currently using about 250MB without any apps installed (I compared memory usage with tomcat stopped and running), and I also need to run lighttpd and mysql. Is there any way to get that number down? I don't need it to be able to handle a large number of requests at once.
