• CORS Fails on CloudFront Distribution with Nginx Origin

  - by kgrote

  I have a CloudFront distribution set up with an Nginx server as the origin (a Media Temple DV server, to be specific). I enabled the Access-Control-Allow-Origin: * header so fonts will work in Firefox. However, Firefox throws a CORS error for fonts loaded from this CloudFront/Nginx distribution. I created another CloudFront distribution, this time with an Apache server as the origin, and set Access-Control-Allow-Origin: * also. Firefox displays fonts from this origin without issue. I've set up a demo page here: http://kristengrote.com/cors-test/ When I perform a curl request for the same font file from each distribution, both files return almost exactly the same headers: Apache Origin Nginx Origin ——————————————————— ——————————————————— HTTP/1.1 200 OK HTTP/1.1 200 OK Server: Apache Server: nginx Content-Type: application/font-woff Content-Type: application/font-woff Content-Length: 25428 Content-Length: 25428 Connection: keep-alive Connection: keep-alive Date: Wed, 11 Jun 2014 23:23:09 GMT Date: Wed, 11 Jun 2014 23:15:23 GMT Last-Modified: Tue, 10 Jun 2014 22:15:56 GMT Last-Modified: Tue, 10 Jun 2014 22:56:09 GMT Accept-Ranges: bytes Accept-Ranges: bytes Cache-Control: max-age=2592000 Cache-Control: max-age=2592000 Expires: Fri, 11 Jul 2014 23:23:09 GMT Expires: Fri, 11 Jul 2014 23:15:23 GMT Access-Control-Allow-Origin: * Access-Control-Allow-Origin: * Access-Control-Allow-Methods: GET, HEAD Access-Control-Allow-Methods: GET, HEAD Access-Control-Allow-Headers: * Access-Control-Allow-Headers: * Access-Control-Max-Age: 3000 Access-Control-Max-Age: 3000 X-Cache: Hit from cloudfront X-Cache: Hit from cloudfront Via: 1.1 210111ffb8239a13be669aa7c59f53bd.cloudfront.net (CloudFront) Via: 1.1 fa0dd57deefe7337151830e7e9660414.cloudfront.net (CloudFront) X-Amz-Cf-Id: QWucpBoZnS3B8E1mlXR2V5V-SVUoITCeVb64fETuAgNuGuTLnbzAhw== X-Amz-Cf-Id: E2Z3VOIfR5QPcYN1osOgvk0HyBwc3PxrFBBHYdA65ZntXDe-srzgUQ== Age: 487 X-Accel-Version: 0.01 X-Powered-By: PleskLin X-Robots-Tag: noindex, nofollow So the only conclusion I can draw is that something about Nginx is preventing Firefox from recognizing CORS and allowing the fonts via CloudFront. Any ideas on what the heck is happening here?

• MySQL Error: FUNCTION LEVENSHTEIN already exists

  - by kgrote

  I've got an ExpressionEngine database and I exported a couple of tables from it, then dropped those tables. When I try to re-import the tables in PHPMyAdmin, I get this error: SQL query: -- -- Database: `my_db` -- DELIMITER $$ -- -- Functions -- CREATE DEFINER=`my_username`@`%` FUNCTION `LEVENSHTEIN`(s1 VARCHAR(255), s2 VARCHAR(255)) RETURNS int(11) DETERMINISTIC BEGIN DECLARE s1_len, s2_len, i, j, c, c_temp, cost INT; DECLARE s1_char CHAR; DECLARE cv0, cv1 VARBINARY(256); SET s1_len = CHAR_LENGTH(s1), s2_len = CHAR_LENGTH(s2), cv1 = 0x00, j = 1, i = 1, c = 0; IF s1 = s2 THEN RETURN 0; ELSEIF s1_len = 0 THEN RETURN s2_len; ELSEIF s2_len = 0 THEN RETURN s1_len; ELSE WHILE j <= s2_len DO SET cv1 = CONCAT(cv1, UNHEX(HEX(j))), j = j + 1; END WHILE; WHILE i <= s1_len DO SET s1_char = SUBSTRING(s1, i, 1), c = i, cv0 = UNHEX(HEX(i)), j = 1; WHILE j <= s2_len DO SET c = c + 1; IF s1_char = SUBSTRING(s2, j, 1) THEN SET cost = 0; ELSE SET cost = 1; END IF; SET c_temp = CONV(HEX(SUBSTRING(cv1, j, 1)), 16, 10) + cost; IF c > c_temp THEN SET c = [...] MySQL said: Documentation #1304 - FUNCTION LEVENSHTEIN already exists I get this error even if I drop all tables from the DB and try to import anything. The only way I can get the error to go away is to totally delete the database and re-create it. What's causing that error and how can I stop it from happening?

• RewriteRule Works With "Match Everything" Pattern But Not Directory Pattern

  - by kgrote

  I'm trying to redirect newsletter URLs from my local server to an Amazon S3 bucket. So I want to redirect from: https://mysite.com/assets/img/newsletter/Jan12_Newsletter.html to: https://s3.amazonaws.com/mybucket/newsletters/legacy/Jan12_Newsletter.html Here's the first part of my rule: RewriteEngine On RewriteBase / # Is it in the newsletters directory RewriteCond %{REQUEST_URI} ^(/assets/img/newsletter/)(.+) [NC] # Is not a 2008-2011 newsletter RewriteCond %{REQUEST_URI} !(.+)(11|10|09|08)_Newsletter.html$ [NC] ## -> RewriteRule to S3 Here <- ## If I use this RewriteRule to point to the new subdirectory on S3 it will NOT redirect: RewriteRule ^(/assets/img/newsletter/)(.+) https://s3.amazonaws.com/mybucket/newsletters/legacy/$2 [R=301,L] However if I use a blanket expression to capture the entire file path it WILL redirect: RewriteRule ^(.*)$ https://s3.amazonaws.com/mybucket/newsletters/legacy/$1 [R=301,L] Why does it only work with a "match everything" expression but not a more specific expression?
