Apache bandwidth tuning in default config
by Tomás 03 Jul '09

03 Jul '09

I've been playing recently with some firefox extensions for web developers: FireBug: https://addons.mozilla.org/es-ES/firefox/addon/1843 PageSpeed: http://code.google.com/intl/es-ES/speed/page-speed/index.html YSlow: http://developer.yahoo.com/yslow/ and found that enabling certain options in the koha's apache VirtualHosts configuration would improve a lot koha's performance in bandwidth use. Only the opac startup page bandwidht usage goes from 368.5K to 118.3K. Enable http compression using mod_deflate --------------------------------------------------------------- Document this command for enabling this in Debian/Ubuntu # a2enmod deflate and add this lines to koha-http.conf in both VirtualHost definitions SetOutputFilter DEFLATE SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip I specify not to apply useless compression to compresed images. Further options could be used. See http://httpd.apache.org/docs/2.0/mod/mod_deflate.html Enable better caching features by setting explicit expiration far in the future for static content using mod_deflate ---------------------------------------------------------------------------------------------------------------------------------------------------------------- Document this command for enabling this in Debian/Ubuntu # a2enmod expires and add this lines to koha-http.conf in both VirtualHost definitions ExpiresActive On ExpiresDefault "modification plus 1 year" as mod_expires only applies to files in the filesystem it is safe to rely on modification date. This could be fine-tuned, for example on a per filetype basis (see http://httpd.apache.org/docs/2.0/mod/mod_expires.html) ----- PageSpeed in particular offers some recommendation on image sizes and provides an optimal image file for substitution. This could be analised. To+. -- Aparición con vida de Jorge Julio López.

Wide character error
by C W Nel 01 Jul '09

01 Jul '09

I staged a record and it imported 100%. I can view it and can see a diacritic (650 7 _aHuérfanos) This record cannot be saved/edited. It gives the “Wide character” error. If I delete the field, it saves 100%. It is obvious that it is not a mysql problem, because it was imported correctly into the database. I tried my best to configure everything to be utf-8, but obviously something is wrong. Can someone please advise? Thanks

Is there an easy way to link a record to a specific URL? With other words to have a hyperlink on a specific record to take you to e.g. an html or pdf file to supply more info on this record? Thanks for any help.
