Editing Rewrite engine (section)

==Web frameworks==
Many web frameworks include URL rewriting, either directly or through extension modules.

* [[Apache HTTP Server]] has URL rewriting provided by the mod_rewrite module.<ref>[http://httpd.apache.org/docs/current/mod/mod_rewrite.html mod_rewrite documentation]</ref>
* URL Rewrite is available as an extension to [[Internet Information Services|Microsoft IIS]].<ref>[http://www.iis.net/download/URLRewrite URL Rewrite extension for Microsoft IIS]</ref>
* [[Ruby on Rails]] has built-in URL rewriting via Routes.<ref>{{cite web|title=Rails Routing from the Outside In|url=http://guides.rubyonrails.org/routing.html|publisher="Ruby on Rails|access-date=25 April 2014}}</ref>
* [[Jakarta Servlet]] has extendable URL rewriting via the OCPsoft URLRewriteFilter and Tuckey UrlRewriteFilter.
* [[Jakarta Faces]] has simplified URL rewriting via the PrettyFaces: URLRewriteFilter.
* [[Django (web framework)|Django]] uses a [[Regular expression|regular-expressions]]-based system. This is not strictly URL rewriting since there is no script to 'rewrite' to, nor even a directory structure; but it provides the full flexibility of URL rewriting.<ref>[http://docs.djangoproject.com/en/dev/topics/http/urls/#id1 Django URLconf]</ref>
* [[Java (programming language)|Java]] [[Stripes (framework)|Stripes Framework]] has had integrated functionality since version 1.5.<ref>[http://greggbolinger.blogspot.com/2008/01/stripes-15-feature-clean-urls.html clean urls in Stripes 1.5]</ref>
* Many Perl frameworks, such as [[Mojolicious]] and [[Catalyst (software)|Catalyst]], have this feature.<ref>[http://mojolicio.us/perldoc?Mojolicious/Guides/Routing Guides - Mojolicious guide to the galaxy]. Mojolicious. Retrieved on 2013-09-08.</ref>
* [[CodeIgniter]] has URL rewriting provided.
* [[lighttpd]] has a mod_rewrite module.<ref>[http://redmine.lighttpd.net/wiki/1/Docs:ModRewrite Docs ModRewrite - Lighttpd - lighty labs]. Redmine.lighttpd.net. Retrieved on 2013-09-08.</ref>
* [[nginx]] has a rewrite module.<ref>{{cite web|url=http://nginx.org/r/rewrite |title=ngx_http_rewrite_module - rewrite |publisher=nginx.org |access-date=25 December 2014}}</ref><ref>{{cite mailing list |date=18 February 2013 |url=http://mailman.nginx.org/pipermail/nginx/2013-February/037592.html |mailing-list=nginx@nginx.org |title=A dynamic web-site written wholly in nginx.conf? Introducing mdoc.su! |first=Constantine A. |last=Murenin |access-date=24 December 2014}}</ref> For example, a multi-link multi-variable page generation from a [[URI]] like [http://mdoc.su/f101,n61,o56,d/ifconfig {{mono|/f101,n61,o56,d/ifconfig}}] is possible, where multiple individual parts like {{mono|f101}} get expanded with the help of [[regular expression]]s into variables to signify {{mono|[[FreeBSD]] 10.1-RELEASE}} and so forth.
* [[Hiawatha (web server)|Hiawatha HTTP server]] has a URL Toolkit which supports URL rewriting.<ref>[http://www.hiawatha-webserver.org/manpages URL TOOLKIT part of Hiawatha webserver's manual]</ref>
* [[Cherokee (Webserver)|Cherokee HTTP server]] supports regular expressions of URL rewriting and redirections.

From a [[software development]] perspective, URL rewriting can aid in code modularization and [[control flow]],<ref>{{cite web|title=Clean URL|url=http://docforge.com/wiki/Clean_URL|publisher=DocForge|access-date=25 April 2014}}</ref>  making it a useful feature of modern web frameworks.
