Free http 500 internal server error software for linux

Bauk HTTP server project is a high-performance Web server. Bauks advanced architecture and unique design provide high performance and many original features, ie. ability to serve unlimited number of Virtual Hosts/simultaneous HTTP connections per single server process without performance loss.
Full installation requires only a single directory of UNIX file system used as a working directory for Bauk executable. Configuration process is simple and performed by adjustment of Bauk configuration script.
Main features:
- Full HTTP/1.1 and CGI/1.1 standard compliance
- HTTP authentication, Basic method, auth script per Virtual Host
- Unlimited number of Virtual Hosts without performance loss
- Virtual Host aliases
- Unlimited number of simultaneous HTTP connections per single Bauk process with no performance loss (Special Edition)
- Persistent (Keep-Alive) connections
- URL Path; define URL and path with type of access; ie. read, write, browse, execute, require HTTP authentication, etc.
- OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE methods of HTTP request defined by HTTP/1.1, configurable per URL Path
- Content negotiation by client language and charset
- Configurable MIME types
- Configurable HTTP headers by MIME type
- Configurable HTML error documents / CGI executables
- Directory browsing; view content of directories with HTML links
- Execution of CGI programs/scripts
- SUID/SGID for CGI execution
- Chroot for CGI execution; chroot CGI to Virtual Hosts home
- 3 security layers for CGI execution: by URL limit to X-only ie. CGI dir; for RX-URL imply X-only for X-able files; impose X-only by file extension ie. CGI executables wrongly placed and no X flag
- Quotas for CGI execution; number of simultaneous CGI processes, execution priority, max execution time (duration), max CPU time, memory, filesize
- Quotas of network traffic in/out per Virtual Host (I/O speed limit)
- Quotas of connections per Virtual Host
- Quotas of connections per client IP number
- Access restriction by IP address; forbid and allow-only
- Access restriction by valid HTTP referrer
- Configurable HTTP-log format and location for Virtual Hosts
- Configurable singleprocess or multiprocess architecture
- Chroot for Bauk server process
- Full configurability; virtually all Bauk features are configurable by simple configuration script adjustment
- Easy configuration by script language; built-in configuration script interpreter with preprocessor, file-inclusion, block and single-line comments, two data types, variables, arithmetic operations and built-in functions
- Easy administration
- Flexibility

HTTP::Server::Simple::Recorder is Perl module for mixin to record HTTP::Server::Simples sockets.

SYNOPSIS

package MyServer;
use base qw/HTTP::Server::Simple::Recorder HTTP::Server::Simple::CGI/;

sub recorder_prefix { "path/to/logs/record" } # defaults to /tmp/http-server-simple-recorder

# logs to path/to/logs/record.34244.1.in,
# path/to/logs/record.34244.1.out,
# path/to/logs/record.34244.2.in,
# path/to/logs/record.34244.2.out, etc, if 34244 is the PID of the server

This module allows you to record all HTTP communication between an HTTP::Server::Simple-derived server and its clients. It is a mixin, so it doesnt itself subclass HTTP::Server::Simple; you need to subclass from both HTTP::Server::Simple::Recorder and an actual HTTP::Server::Simple subclass, and HTTP::Server::Simple::Recorder should be listed first.

Every time a client connects to your server, this module will open a pair of files and log the communication between the file and server to these files. Each connection gets a serial number starting at 1. The filename used is >, then a period, then the connection serial number, then a period, then either "in" or "out". recorder_prefix defaults to /tmp/http-server-simple-recorder, but you can override that in your subclass. For example, you might want to include the process ID.

XML-RPC Client/Server C Library is a cross-platform software written in C that supports persistent HTTP/1.1 conenctions over SSL and comes with XML-RPC interface description language and client/server code compiler. Libxr depends on glib2 and libxml2.
Main features:
- Persistent connections over HTTP/1.1
- SSLv3/TLSv1 using OpenSSL.
- XML-RPC interface description language (XDL).
- XML-RPC client stubs/servlet skels compiler.
- Multiple servlets per server.
- Servlet lifetime (init -- call -- call -- fini).
- Multiplatform (linux, mingw32 on windows).
- IPV6 as soon as OpenSSL 0.9.9 is released.

Server Monitor is a theme which displays the status of your servers. Also you can start / stop them by clicking the names.

You cann add servers by editing the py-file. You may resize theme in the .theme-fille.
