CFHTTP bug?

23 September 2010 02:05 (EST)

Can someone confirm that CF 8/9 throws an error (java.lang.ArrayIndexOutOfBoundsException) on simple CFHTTP call?

<cfhttp method="get" url="http://brad.livejournal.com/" />

StackTrace is following:

java.lang.ArrayIndexOutOfBoundsException: 22

Apparently following call works well:

<cfhttp method="get" url="http://www.livejournal.com/" />

Any thoughts on this?

I think this is a LiveJournal issue or a combination LJ/CF problem, not specifically a CF bug.

I came across your question while poking around on Google to find an answer for my own problem. I have used the following format to get an XML feed of my journal just fine for at least a year with no problem:

Only in the past couple of days have I received the java.lang.ArrayIndexOutOfBoundsException error. I don't know if there's a problem at LJ, or if they purposely changed something that clashes with the ColdFusion tag, but I'm looking for a solution, as well.

If you find an answer, I hope you can post it. I'll bookmark this page and do the same if I find anything.

Hi Todd,

I had no problem fetching LJ data (including RSS) as well, but apparently they have introduced Content-MD5 header on 9 Sep 2010, so CFHTTP tries to calculate MD5 sum and fails.

Have a look for a link from Ed below, we can use Java libs to replace cfhttp until fix is released.

CFHTTP has many "issues" that make it not good enough for all situations. But for this particular example, instead of CFHTTP can be used for example the function i posted here: http://blog.1smartsolution.com//index.cfm/action:posts.entry/id:267/CFHTTP-Frustration

Just checked it and it works fine with the provided URL

Hi Ed,

Many thanks for the link, I will use your workaround until CF is patched.

If you look at the stack trace, I see VerifyMD5 in it -- if you look at the headers from LiveJournal you see:

Content-MD5 GnVmvkAz8R5aaK2e+eZ7FQ

I think that something is up with CF trying to verify the MD5 hash. I see OpenBD CFML engine working just fine -- so it is definitely a CF issue.

Hi Peter,

Yes, LJ has introduced Content-MD5 header on 9 Sep 2010, so CF fails to calculate verification hash. I will submit bug report to Adobe later on today.
