I have a simple "what's my ip" running. It gets called by ajax every 5 seconds.
The php is simply <?php echo $_SERVER['REMOTE_ADDR'];?>
But, looking in the apache server log at requests from the same client, same browser, a table of the size of the frequencies vs the size of requests, shows the output size is not consistent.
I do not use cookies on that site.
467 417
164 570
140 385
40 538
15 4205
4 4173
1 600
1 5834
1 559
1 530
1 2002
How can the size vary? Same question, same answer, I would assume.
... Edit:
When I do curl -i, I get this; size 330. But the size transferred as shown in log is consistently 3956 bytes?!?
The server is on https; so some certificate exchange is being done, still it should be the same?
