PhpDig follows links like any web browser, to build the pages list to index. Links can be in an AreaMap or frames. PhpDig supports relocations. Any syntax of HREF attribute is followed by Phpdig. Simple javascript links like window.open() or window.location() are followed too. PhpDig does not go out the root site you define for the indexing (but see Domain Indexing option). Spidering depth is chosen by user. All html content is listed, both static and dynamic pages. PhpDig searches the Mime-Type of the document.
