[drakma-devel] Strange response message calling http-request
Sometimes I get the response like "Your browser sent a request that this server could not understand". I am scratching my head where this response might be coming from. Probably not from the server I am sending a http-request to.
From what I could find on the net, this message might be coming from an Apache server. I am using hunchentoot behind apache mod_proxy, but drakma has nothing to do with it. I'd appreciate any ideas where this message might be coming from or what would be the best way to debug the problem.
Thank you, Andrew
To be more precise, that's the response (some AkamaiGHost is mentioned here, could it be the culprit?): HTTP/1.0 400 Bad Request Server: AkamaiGHost Mime-Version: 1.0 Content-Type: text/html Content-Length: 215 Expires: Mon, 19 Nov 2007 04:16:16 GMT Date: Mon, 19 Nov 2007 04:16:16 GMT Connection: close "<HTML><HEAD> <TITLE>Bad Request</TITLE> </HEAD><BODY> <H1>Bad Request</H1> Your browser sent a request that this server could not understand.<P> Reference #7.ab0dd58.1195445776.0 </BODY> </HTML> On Nov 18, 2007 10:41 PM, Andrei Stebakov <lispercat@gmail.com> wrote:

After some investigation I starting to understand what's probably going on. The server I am sending requests to is hosted by the Akamai service and because my GET request sends a lot of data (I am sending SVG glyphs information) they may consider it as some kind of DoS attack and try to block it. That's just my guessing... Andrew On Nov 18, 2007 11:22 PM, Andrei Stebakov <lispercat@gmail.com> wrote:

You should try this as a first step: http://weitz.de/drakma/#*header-stream* If that doesn't help, you'll have to look at tools like Wireshark. This is assuming that you're trying to figure out if Drakma does the right thing. Of course, you can't really debug the server from your Lisp image... :) Edi.
