Cross Domain AJAX - A quick anatomy of a mashup

September 19th, 2007 by Aaron

So after searching the Internet for some cross domain AJAX stuff, I noticed two interesting articles. The first was the specifics of writing these queries (located here). Then, the next gave a breakdown of how this might be useful in a mash-up collaborative sense (here).

The one missing point was how the collaboration should occur. There is talk about same parent domain but I think everyone’s forgetting about the DNS/webserver changes that need to happen.

In order to prove my concept on my windows box, I set up the examples. In that previous example, domain D had a subdomain of D_s which pointed to E.

I determined what the IP address of E was and entered that into my hosts file (I don’t have access to a DNS server at the moment) followed by the subdomain D_s.

Next, using apache, I found the virtual host for E, and put in ‘ServerAlias D_s’. This will make sure that the incoming connection to that IP will also respond to that sub domain.

I just wanted to jot this down to help fill in the hole I noticed.

Pass PHP session to a new script using fsockopen

I was working on a script that opened up a new connection to the same server with fsockopen to process a php script. It passed the variables needed through GET and then gathered the output. Finally, it displayed the output on the screen under the current context.

I ran into an issue where now I needed to set a session variable in my calling script, but make the same session information available to the called script (the called script starts its own session too).

This is how I did it:

Security Issue with Subversion Deployment?

July 4th, 2007 by Aaron

I use Subversion (SVN) for source control and deployment both for JEMDiary and at (”the triangle”). While working on my local copy of one of the websites, I got to thinking about the .svn folder and all of its files. The .svn folder is a local cache/db of the file changes in order to support diffs, reverts, and to give cues about file changes and the need to commit. I started poking around inside of the folder - and discovered the text-base folder. Inside of there, every one of my recently changed files were in there with an extension of .svn-base. Could this be a security issue - was I showing my code to the whole world? Lets figure this out:
