--------------------
-
-.. module:: scrapy.downloadermiddlewares.ajaxcrawl
-
-.. class:: AjaxCrawlMiddleware
-
-   Middleware that finds 'AJAX crawlable' page variants based
-   on meta-fragment html tag.
-
-   .. note::
-
-       Scrapy finds 'AJAX crawlable' pages for URLs like
-       ``'http://example.com/!#foo=bar'`` even without this middleware.
-       AjaxCrawlMiddleware is necessary when URL doesn't contain ``'!#'``.
-       This is often a case for 'index' or 'main' website pages.
