.SH "NAME"
Perlbal::Manual::WebServer \- Configuring Perlbal as a Web Server
.SS "\s-1VERSION\s0"
.IX Subsection "VERSION"
Perlbal 1.78.
.SS "\s-1DESCRIPTION\s0"
.IX Subsection "DESCRIPTION"
How to configure a Perlbal Web Server service.
.SS "\s-1READ\s0 \s-1ME\s0 \s-1FIRST\s0"
.IX Subsection "READ ME FIRST"
Please read Perlbal::Manual::Configuration first for a better explanation on how to configure Perlbal. This document will make much more sense after reading that.
.SS "Configuring Perlbal as a Web Server"
.IX Subsection "Configuring Perlbal as a Web Server"
By default, perlbal looks for a configuration file at \fI/etc/perlbal/perlbal.conf\fR.
.PP
You can also point perlbal at a different configuration file with the \fB\-c\fR flag.
.PP
.Vb 1
\&    $ perlbal \-c /home/user/perlbal.conf
.Ve
.PP
Here's a very simple example where we configure a simple web server that serves an index file under /tmp
.PP
.Vb 5
\&    CREATE SERVICE perlbal_test
\&        SET role           = web_server
\&        SET listen         = 0.0.0.0:80
\&        SET docroot        = /tmp
\&    ENABLE perlbal_test
.Ve
.PP
The first line creates a service called \f(CW\*(C`perlbal_test\*(C'\fR. The last line enables that service.
.PP
The three parameters state \- in order \- that the service is a web server, that it listens on all addresses on port 80, and that its document root is \f(CW\*(C`/tmp\*(C'\fR.
.SS "Parameters"
.IX Subsection "Parameters"
You can set parameters via commands of either forms:
.PP
.Vb 2
\&    SET <service\-name> <param> = <value>
\&    SET <param> = <value>
.Ve
.IP "\fBdirindexing\fR = bool" 8
.IX Item "dirindexing = bool"
Show directory indexes when an \s-1HTTP\s0 request is for a directory. Warning: this is not an async operation, so will slow down Perlbal on heavily loaded sites.
.Sp
Default if false.
.IP "\fBdocroot\fR = directory/root" 8
.IX Item "docroot = directory/root"
Directory root for web server.
.IP "\fBenable_concatenate_get\fR = bool" 8
.IX Item "enable_concatenate_get = bool"
Enable Perlbal's multiple-files-in-one-request mode, where a client have use a comma-separated list of files to return, always in text/plain.
.Sp
Useful for web apps which have dozens/hundreds of tiny css/js files, and don't trust browsers/etc to do pipelining.
.Sp
Decreases overall round-trip latency a bunch, but requires app to be modified to support it. See t/17\-concat.t test for details.
.Sp
Default is false.
.IP "\fBenable_md5\fR = bool" 8
.IX Item "enable_md5 = bool"
Enable verification of the Content\-MD5 header in \s-1HTTP\s0 \s-1PUT\s0 requests.
.Sp
Default is true.
.IP "\fBenable_delete\fR = bool" 8
.IX Item "enable_delete = bool"
Enable \s-1HTTP\s0 \s-1DELETE\s0 requests.
.Sp
Default is false.
.IP "\fBenable_put\fR = bool" 8
.IX Item "enable_put = bool"
Enable \s-1HTTP\s0 \s-1PUT\s0 requests.
.Sp
Default is false.
.IP "\fBindex_files\fR = comma-separated list of filenames" 8
.IX Item "index_files = comma-separated list of filenames"
Comma-separated list of filenames to load when a user visits a directory \s-1URL\s0, listed in order of preference.
.Sp
Default is index.html.
.IP "\fBmax_put_size\fR = size" 8
.IX Item "max_put_size = size"
The maximum content-length that will be accepted for a \s-1PUT\s0 request, if enable_put is on.
.Sp
Default is 0, which means there is no limit.
.IP "\fBmin_put_directory\fR = int" 8
.IX Item "min_put_directory = int"
If \s-1PUT\s0 requests are enabled, require this many levels of directories to already exist. If not, fail.
.Sp
Default is 0.
.IP "\fBserver_tokens\fR = bool" 8
.IX Item "server_tokens = bool"
Whether to provide a \*(L"Server\*(R" header.
.Sp
Perlbal by default adds a header to all replies (such as the web_server role). By setting this default to \*(L"off\*(R", you can prevent Perlbal from identifying itself.
.Sp
Default is \f(CW\*(C`on\*(C'\fR.
