LSWS 4.1.13 + Kayako Support Suite (and possibly other scripts)

[MikeDVB]

When LSWS 4.1.13 is running, none of the web forms in Kayako SupportSuite work - they all return error messages about not submitting a department ID, or not entering a search query, etc... When I roll back to 4.1.12 this issue disappears entirely and the site/script/forms work as expected.

The PHP version and binaries are the same and have not changed, but we are running PHP 5.3.14.

This *appears* from the debug logging to me, to be a mod_rewrite issue. The logs indicate in 4.1.13 that it's doing a 301 permanent move where as 4.1.12 does not indicate this and does further processing. There are no mod_rewrite rules in the .htaccess, however:

root@redacted [/home/redacted/public_html_other/redacted.com/support]# cat .htaccess
php_flag display_errors on
php_flag register_globals on
php_value max_execution_time 600
php_value memory_limit 512M
php_value max_input_time 600
php_flag file_uploads on
php_value upload_max_filesize 20M
php_value max_file_uploads 20

Here is the POST request of one of the forms that doesn't work on 4.1.13:

4.1.13 - Apparently it's rewriting the URL
