Tips and Tricks for Apache

Using Fast-CGI

• Check that your TinyOWS is compiled with FastCGI support:

  [user@host mapserver]$ tinyows --check
  TinyOWS version:   1.1.0
  FCGI support:      Yes
  ...

Fast-CGI in Apache

• In Apache, activate mod_fastcgi

  $ sudo apt-get install -y libapache2-mod-fastcgi
  $ sudo a2enmod fastcgi

• Apache fast-cgi configuration:

  #in your cgi-bin directive, add the following to run all cgi-bin using FastCGI
  SetHandler fastcgi-script
  
  #in your FastCGI config file (typically something like /etc/apache2/mods-enabled/fastcgi.conf)
  FastCgiServer /usr/lib/cgi-bin/tinyows.fcgi -processes 10

Fast-CGI in MS4W

• Please refer to the fastcgi doc in ms4w

• Add the following 2 lines:

  DefaultInitEnv TINYOWS_CONFIG_FILE "/ms4w/apps/tinyows/config.xml"
  DefaultInitEnv TINYOWS_SCHEMA_DIR "/ms4w/apps/tinyows/schema/"

HTTP GZip compression

• In Apache, activate mod_deflate

• Deflate basic configuration, (note we’re including xml so gml and json):

  AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml application/json
