Performance

[NOTE: This module has been deprecated as of June 2013 in favor of Cache Expiration. If you're currently using Boost Expire, please follow these directions to switch from Boost Expire to Cache Expiration on your site!]

A cache expiration module to go with Boost for Drupal 7.

Currently, Boost for Drupal 7 doesn't do any active cache expiration (see #1069438: How to Flush Boost Cache in Drupal 7.x), and this means that when you update a node, post a comment, etc., Boost will continue serving stale content from its static HTML cache until the file is finally cleaned up on a cron run.

For many sites, especially smaller sites where content is updated infrequently and cron may be run hourly or even less frequently, this means stale content will be served for quite some time, unless someone visits the Performance page and clears all the site's caches manually.

This module alleviates that problem by simply flushing Boost's static HTML cache every time a node or comment is posted or updated. You can set the module to respect your site's Minimum cache lifetime so it doesn't flush the cache until the minimum lifetime has passed.

This module may become deprecated in favor of a more universal solution (like Boost integration with the Cache Expiration module).

In brief, this project could help you rewrite the URLs.

1. sub urls of node and user will be rewritten when the parent url has an alias.
2. you can use regex to rewrite any url if you want

NOTICE: no need to enable this module, just include the core in your settings.php

In Drupal, we have node and user. In many cases, node|user has many sub-tab menu, such as node/%/info node/%/devel and any other MENU_LOCAL_TASK.
If you use url_alias, you need to add alias for each of them. This module, Rewrite Sub Link, will help you rewrite them automatically, and which doesn't user url_alias, so when you have millions of node, it won't case a performance issue.

Additionally, this module support regular express, so you can write your regular express to change your URL.

Light-weight Usage
add this line in the settings.php file,
include_once "sites/all/modules/contrib/rewrite_sub_link/rewrite_sub_link.core.inc";
add your custom settings in your settings.php
include_once "path_to_your_custom_rewrite_settings.php"
or change the code in rewrite_sub_link/rewrite_settings.php directly.

then all the sub links of user and node will be rewritten automatically.
Please check rewrite_settings.php file and change for your custom settings.

This module provides information blocks, regarding replication status between MySQL masters and slaves.

This is a simple module to export redirects to Apache rules.

Apache rules will be faster than Drupal can be, and if put in version control perhaps more maintainable over the long term.

A module that circumvents core CSS and JS aggregation. No regex hacks or any other fragile things.

Generic and abstract, backend agnostic storage API.

This aims to provide a fully featured storage layer, providing API's depending on the storage type you want to use:
