For the last few days, I've been getting occasional 404 errors when I try to display images, whose URLs are taken the GData Picasa output, to users in a standard browser. Is this the correct place to report an issue like this?
The 404 message is somewhat random. The image will load fine one minute, then fail the next (even after refresh). If I switch to a different browser, the image loads up correctly, even while it's failing in the other browser! Here's an example URL. I used the Picasa query API to search for "test" and picked one of the items out: http://lh6.ggpht.com/_FNZsyfYpnCU/SRxMI7865wI/AAAAAAAAyTI/e7mtBDLuakI/IMGA0187.JPG I ran tcpdump on an unsuccessful session and got this: ----------------------------------------------------- Unsuccessful session #1 (firefox) ----------------------------------------------------- 15:24:47.789886 IP (my machine).59698 > pz-in-f93.google.com.http: P 527:1054(527) ack 1555 win 33323 <nop,nop,timestamp 903941105 76787118> E..C>....@[email protected]}.].2.P.QO........+.>..... 5.......GET /_FNZsyfYpnCU/SRxMI7865wI/AAAAAAAAyTI/e7mtBDLuakI/ IMGA0187.JPG HTTP/1.1 Host: lh6.ggpht.com User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv: 1.9.0.10) Gecko/2009042315 DotSpots/20090522-1241 Firefox/3.0.10 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: (redacted) Cache-Control: max-age=0 15:24:47.832378 IP pz-in-f93.google.com.http > (my machine).59698: . 1555:2973(1418) ack 1054 win 24 <nop,nop,timestamp 76793819 903941105> E.......5..QJ}.].....P.2.....QQ.....I...... ....5...HTTP/1.1 404 Not Found Content-Type: text/html; charset=UTF-8 Date: Fri, 22 May 2009 21:24:47 GMT Server: fife Content-Length: 1415 <html><head> <meta http-equiv="content-type" content="text/html;charset=utf-8"> <title>404 Not Found</title> (rest of 404 snipped) ----------------------------------------------------- I then opened up Safari, ran the same query and it succeeded.
