I lied. It's not by IP.
Suddenly URL's with + or %20 don't work. From php Curl, but work from IE and Chrome. From: [email protected] [mailto:[email protected]] On Behalf Of Brandon Wirtz Sent: Saturday, December 24, 2011 12:52 AM To: [email protected] Subject: [google-appengine] Getting 400 Errors only to Certain IP's It appears that my IP is occasionally getting blocked with 400 Errors when doing a CURL from PHP. Looks like a "soft" DOS block? This is particularly bad because when we then serve the page on the PHP side we are serving the Google branded 400 which I'm sure can't be good for SEO. I'm hesitant to post too much about the error because we use this app as a Data Cache and we have been too lazy to put "real" security on it. So at this point I'm just asking is there some mechanism GAE uses to auto detect "DOS" attacks and block the IP? And is this new? And Why is it 400 instead of 500? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
