What does 'Zero sized reply' mean?

Question

So I've been getting this message whenever I try to view Livejournal pages while signed into my LJ account:

While trying to retrieve the URL: http://www.livejournal.com/
The following error was encountered:
Zero Sized Reply
Squid did not receive any data for this request.
Your cache administrator is root.

I noticed this only appears when I view LJ pages when I'm signed in LJ. The pages turn up fine once I'm logged out of the account, and I've checked every other website I frequent. They all turn up okay for me. This is also true across all browsers.

Any way of resolving this? I've tried clearing my cookies etc, but the problem persists. Is it possible my account's gotten hacked?

Technically, it means that the web process handling your request closed the connection without returning any data at all, not even HTTP headers. (It sent a "zero-sized reply.")



Unfortunately, there are a number of completely different reasons why this might happen that need to be investigated individually.



If the error message takes a very long time to be displayed (a minute or more), it may just be that the system got tired of waiting for a script or CGI application to respond. In this case, try to identify what's making your script run so slowly.



If the error message appears instantly, it probably means something is aborting the connection. If you receive this error from a CGI script, it may mean that your script (or its interpreter, if applicable) is core dumping. There is a known problem on our system where you can get this error running threaded Python applications on our 64-bit servers; let us know if that happens to you and we'll move you to a 32-bit server.



To help debug this problem, make sure you have your error log enabled. If it happens immediately and there are no error log entries, it may be a core dump. In that case, find a public URL that does it reproducibly and submit it to us in a secure support request; we can check the system logs to find out if requests for that URL are indeed core dumping. If there are error logs, they will probably help identify the problem.



If you are running into this problem on a PHP site, it may help to add the following lines to your .htaccess file:



php_value pcre.recursion_limit 1000

php_value pcre.backtrack_limit 1000

The specific values to use vary from site to site. Some require settings as low as 10, others may be fine with 100000. You want the largest value that you can set without triggering the zero-sized reply. This is caused by a PHP/PCRE bug and is not under our control.

Answer 3

If your naturally that thin, the only thing I can think of for you to gain weight is to eat a LOT more than normal. You must have a very high metabolism, so eat a lot more than normal.. and drink Whey protein shakes, etc to gain a little muscle weight.. and help tone up some... Count how many calories you have a day now, and then double that... You should gain weight then, but it may be at a slow pace.. So be patient.. Once you get at the size you want, cut your calorie intake down a bit, so you don't continue to gain... The part I don't understand is, most girls would DIE to be a size 0, and try with all there might to lose down to that, but your wanting to GAIN weight.. lol.. which probably isn't a bad thing, some people prefer girls who have a little meat on there bones, over stick thin girls.. Hope I helped! Best wishes! :-)
