<h3>Bug Fixes</h3>
<p>10/17/08 - Fixed known bugs..  Improved Testing with debug output automatically for failed tests.</p>
<p><br class="clear" /></p>

<h3>Backups and Revisioning</h3>
<p>8/19/08 - Ok so version 4.6 has some nice automatic revisioning/backup features... the next release will let us compare the new .htaccess file with the old .htaccess files just like wikis.  (based once again on wordpress core)..</p>
<p>So now that the SID module system is pretty stable and there is now decent backups going on, the next thing I'll be adding is multi-user and group management.  And much more access control by IP address and other ids.</p>
<p>The point of doing all that is so the plugin will be stable enough code-wise so we can focus in on developing custom SIDs for protecting wordpress blogs.. Mod_Security rules are on the way....</p>
<p><br class="clear" /></p>

<h3>The SID Module Redesigned</h3>
<p>8/14/08 - I'm finally mostly happy with the system now used by this plugin to update/modify/and use the different modules.  The old code just wasn't future-proofed enough.  This new version is based very much off of the WordPress Plugins code, so it is future proofed.</p>
<p>This "Improvements" page is the start of whats to come, Basically each of the security modules (and there are a LOT of great mod_security ones coming) will have their own very Basic settings.  So you can tweak the settings.  If someone finds an improvement they can send it for review.  New ideas and modules can be submitted here also.</p>

<h2>Warning!</h2>
<p>If like me you install plugins without reading the instructions and browsing the source first, please be warned that once activated and a security module is also activated, you can easily lock YOURSELF out of your /wp-admin/ folder, in some cases you may even disable your site.  The fix is easier than you can imagine.  This plugin ONLY edits 2 files.  The .htaccess file in the directory where your wp-config.php file is located, and the .htaccess file in the directory /wp-admin/.  ALL you have to do to start over is to remove the obvious AskApache Section from those files.  That's it.  This plugin doesn't modify files, modify your database, modify your rewrites, it only modifies the server.  If the following harmless tests are not successful, PLEASE prepare yourself by learning how to access your server files via FTP/SFTP/SSH/WebDav/WEbFTP/etc. so that if you do have a problem you can edit those 2 files and prevent downtime.</p>
<p>UNDERSTAND: That this is not like any other security plugins that operate at the application-level by controlling or using PHP to stop attacks, this plugin works at the network-level BEFORE PHP, which is why this plugin is so effective.  It works so well that I had to write this extreme warning message as literally thousands of blog admins who installed this plugin locked down their whole blog to the point that they themselves were locked out.  I've had to screen thousands of emails from panicked users who locked themselves out, it's such an easy fix I won't reply to them.  <strong>2... Only 2..</strong> Files are changed by this plugin and simply removing the AskApache Section from each file will return your site to 100% the way it was, <strong>deleting this plugin on a broken blog does nothing, as this works above PHP all you need to do is edit those 2 files.</strong>.</p>
<h2>New Version Soon!</h2>
<p>For those who've been using this plugin since 2007, and everyone who is waiting for my updates, THIS IS NOT IT, this is not even close. ;)  As more people use this plugin I felt I had to make some changes to prevent all the support emails.  The future 4.7 release is 2 years in the making, and I assure you will blow you away when it's released.  If any PHP developers out there want to help me finish it up or beta test, email me at webmaster@askapache.com (serious only, I can use the help).</p>
<h2>Test for Compatibility and Capability</h2>
<form action="options-general.php?page=askapache-password-protect.php" method="post"><?php wp_nonce_field( 'askapache-passpro-form' );?>
<input type="hidden" id="a_step" name="a_step" value="test" />
<p>First we need to run a series of tests on your server to determine what capabilities your site has and also to locate any potential installation problems.</p>
<p>The tests will be run on temporary files I'll create in your <?php echo dirname(__FILE__).'/tests';?> folder.  They will create .htaccess and .htpasswd files in that location and then use fsockopen networking functions to query those files.  This tells us exactly how your server handles .htaccess configurations, HTTP authentication schemes, Apache Module capability, etc..</p></p>

<table class="form-table">

<p>Several tests send specially crafted HTTP requests which are designed to elicit very specific HTTP Protocol Responses to accurately determine your servers capabilities.</p>
<p>Other important checks will run:  file permissions, function availability, much more boring testing.  The tests are fast and you can re-run them whenever you want.   If you'd like to see the action, define AA_PP_DEBUG to 1 in the source of this file. Good Luck!</p>

<h2>Test Results</h2>

<br /><br /><h2 style="font-size:16px;">Required Checks</h2>
<p>The tests performed by this page are currently required to determine your servers capabilities to make sure we don't crash your server.  The utmost care was taken to make these tests work for everyone running Apache, which is crazy hard because we are testing server configuration settings programmatically from a php binary without access to server configuration settings.</p>
<p>So we achieve this by modifying your server's .htaccess configuration file and then making special HTTP requests to your server which result in specific HTTP responses which tell us if the configuration changes failed or succeeded.  The most widely allowed (by web hosts) and compatible 4+5 php function that provides access to sockets is fsockopen, so it is required.  The next version will fallback to curl, but if your web host has disabled fsockopen you can bet you don't have curl.</p>

<br /><br /><h2 style="font-size:16px;">File Permission Tests</h2>
<p>If any of these checks fail this plugin will not work.  Both your /.htaccess and /wp-admin/.htaccess files must be writable for this plugin, those are the only 2 files this plugin absolutely must be able to modify.  If any of the other checks fail you will need to manually create a folder named askapache in your /wp-content/ folder and make it writable.</p>

<p>These tests determine with a high degree of accuracy whether or not your server is able to handle .htaccess files, and also checks for various Apache modules that extend the functionality of this plugin.

<h2>Test Results</h2>

<br /><br /><h2 style="font-size:16px;">Required Checks</h2>
<p>The tests performed by this page are currently required to determine your servers capabilities to make sure we don't crash your server.  The utmost care was taken to make these tests work for everyone running Apache, which is crazy hard because we are testing server configuration settings programmatically from a php binary without access to server configuration settings.</p>
<p>So we achieve this by modifying your server's .htaccess configuration file and then making special HTTP requests to your server which result in specific HTTP responses which tell us if the configuration changes failed or succeeded.  The most widely allowed (by web hosts) and compatible 4+5 php function that provides access to sockets is fsockopen, so it is required.  The next version will fallback to curl, but if your web host has disabled fsockopen you can bet you don't have curl.</p>

<p>If any of these checks fail this plugin will not work.  Both your /.htaccess and /wp-admin/.htaccess files must be writable for this plugin, those are the only 2 files this plugin absolutely must be able to modify.  If any of the other checks fail you will need to manually create a folder named askapache in your /wp-content/ folder and make it writable.</p>
