Their just looking for a way in.
I see similar entries in my logs along with every variation of phpinfo, dbadmn, websql, phpMyAdmin, etc. Their directory searches of my domains also include many system defaults like /htdocs, /admin, /xampp and directories used by WYSIWYG design tools along with extension .htm and .html. They also do GETs to all directories (domain/directory/) letting the host system find any index/Welcome file with what ever extension.
They are just looking for a weakness. A "well behaved" spider would just follow sitemap.xml or links in your files, not looking around for test files, tools or things left behind from design changes. But all domain traversals are not well behaved.
