.htaccess, mod rewrite and forward slashes

Posted on February 18, 2012 by cronsystems

we had forward slashes in our user-generated URLs that caused 404 errors.

e.g. http://domain.com/products/Prom%2FHomecoming+dress

after several g searches we were able to piece it together. recent releases of apache allow sys admin’s to use allowencodedslashes for each virtual host. thing is it can’t be added to .htaccess like so:

Allowencodedslashes on

http://serverfault.com/questions/295664/mod-rewrite-not-working-with-url-encoded-values

It needs to be added to Apache as a VirtualHost definition. Lovely, how do we do that? Well, we found this:

Putting all these pieces together fixed this issue.

actionscript socket data and no response from socket server

Posted on January 19, 2012 by cronsystems

sending btye arrays to and from the client/server via actionscript’s socket class may not return a result from the server.

the issue is when sending data to the server it must have the \r\n at the end of the string.

socket.writeUTFBytes(username.text + password.text + "\r\n");

cannot login to linux server via ssh

Posted on December 9, 2011 by cronsystems

we knew the hostname, username, password, port, etc. we’re all correct. they had been working just fine. then one day putty and ftp via ssh stopped working.

the culprit is fork bomb protection. to fix we had to increase the number of processes each user could run. to do this we added the following to etc -> security -> limits.conf as root

user1 soft nproc 40
user2 soft nproc 40

after making the updates we restarted the service that controlled the most processes.

mysql, select in, join()

Posted on November 12, 2011 by cronsystems

we needed to use SELECT first_name FROM tbl_users WHERE city IN (‘chicago’,'new york’). chicago,new york was a comma delimited string with no spaces and no single quotes. we used join() to add the single quotes.

$sql = "SELECT city FROM tbl_city WHERE city_name ='".$_POST['city_name']."' AND active = 'Y'";
$result = dbQuery($sql);
$row = dbFetchAssoc($result);
$explode_city = explode(",",$row['city']);
$ids = join("','",$explode_city );
$sql2 = "SELECT first_name FROM tbl_users WHERE city IN ('".$ids."')";
