Having percent sign inside URL, returns bad request (error 400) to the browser. I have a file name that have percent (%) sign, resides at server.
Original File name: 204153_20090605_Aluminiumacetotartraat_DCB_oordruppels_1,2%.pdf
Url in browser after clicking on download link:
http://www.example.com/204153_20090605_Aluminiumacetotartraat_DCB_oordruppels_1%2C2%25.pdf
This returns 400 error with bad request. I am using Kohana 3.
Existing .htaccess file contents are as follows:
RewriteEngine On
RewriteBase /
<Files .*>
Order Deny,Allow
Deny From All
</Files>
RewriteRule ^(?:application|modules|system)\b.* index.php/$0 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT]
回答1:
Try the B flag to ensure the %25, unescaped to % by mod_rewrite, is re-escaped back to %25 when inserted back into the target path.
RewriteRule .* index.php/$0 [PTB]
