• Solr JNDI configuration

    17-01-2011Author: basdenooijer 2 Comments

    As a follow-up on my previous post Solr XML config includes I want to point out another good way to handle environment specific Solr settings: using JNDI. This is not a replacement for XML includes, but in cases where you just need a custom database connection or Solr home dir it might be better suited. [...]

    For an opensource project I’m working on I need a good Solr test dataset. More info about the project will follow soon, but as a teaser I can already tell it’s Solr and PHP related The dataset needs to be of a reasonable size (not unrealisticly small, but not huge either) and it should be [...]

  • Solr XML config includes

    30-10-2010Author: basdenooijer Add a comment

    If you ever used Solr in a version controlled project you will probably have run into the same issues as I have: the solr config files contain definitions that you want to have in version control, but they also contain environment specific settings. You can use the version controlled configs as a distribution version which [...]

    TLS/SSL encryption is generaly a good thing to use, however it can in some cases be hard to implement. Stunnel is a small program that provides SSL/TLS capabilities to clients and/or servers that don’t speak SSL/TLS natively. It basically works like a proxy, transparently adding an encryption layer to the communication layer; or removing it. [...]

  • Cross-domain XHR with Varnish

    09-07-2010Author: basdenooijer Add a comment

    Cross-domain XHR (AJAX) requests can be an issue. There are workarounds like JSONP but sometimes JSONP is not available, or you need a POST request, or you have other special requirements that require usage of XHR. In that case a webproxy on your own domain is often used to resolve the crossdomain issue. There are [...]

  • Complex Solr faceting

    08-07-2010Author: basdenooijer 2 Comments

    When using Solr faceting sooner or later there will be a request for a complex facet, one that at first sight seems impossible using standard Solr faceting. However with some creative use of facets and a small bit of extra logic in your application you can create a very advanced faceting interface. In this example [...]

  • Controlling Varnish ESI inside your application

    05-07-2010Author: basdenooijer 2 Comments

    For me one of the best features of Varnish is ESI (Edge Side Includes).  It allows you to combine elements with different lifetimes into a single page. This way you don’t need to regenerate a complete page as soon as a news listing somewhere on the page changes. And you can still cache pages while [...]
