292419 - The browser permanently sends duplicated GET requests to my site

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Mikhail A.Golovanov]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.7)

The browser permanently sends du0plicated GET requests to my site which in some 
cases has catastrophic results (for example, when  GET request launches a 
backgroung process). Typical example (taken from my localhost site 
installation):

First request
======================================

method          = GET
protocol        = HTTP/1.1
requestURI      = /amazon/account.do
remoteAddr      = 127.0.0.1
remoteHost      = 127.0.0.1
serverName      = localhost
serverPort      = 80
remoteUser      = 
authType        = 
queryString     = null
scheme          = http
secure          = false
contentLength   = 0
contentType     = null
attributes      = {}
headers         = === MimeHeaders ===
accept = 
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,
image/png,*/*;q=0.5
accept-language = ru-ru,ru;q=0.5
connection = keep-alive
host = localhost
referer = http://localhost/amazon/home.do
user-agent = Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.7) 
Gecko/20050414 Firefox/1.0.3
cookie = JSESSIONID=13A7D0EF0EAE147355EED9BC4E585A83
accept-encoding = gzip,deflate
accept-charset = windows-1251,utf-8;q=0.7,*;q=0.7
keep-alive = 300
content-length = 0
cookies         = === Cookies ===
Cookie JSESSIONID=13A7D0EF0EAE147355EED9BC4E585A83 ; 0 null null
======================================

response is 200 OK, everything looks fine... and the browser immediately sends 
another GET to the same URI:

Second (duplicated)  request
======================================

method          = GET
protocol        = HTTP/1.1
requestURI      = /amazon/account.do
remoteAddr      = 127.0.0.1
remoteHost      = 127.0.0.1
serverName      = localhost
serverPort      = 80
remoteUser      = 
authType        = 
queryString     = null
scheme          = http
secure          = false
contentLength   = 0
contentType     = null
attributes      = {}
headers         = === MimeHeaders ===
accept = image/png,*/*;q=0.5
accept-language = ru-ru,ru;q=0.5
connection = keep-alive
host = localhost
referer = http://localhost/amazon/account.do
user-agent = Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.7) 
Gecko/20050414 Firefox/1.0.3
cookie = JSESSIONID=13A7D0EF0EAE147355EED9BC4E585A83
accept-encoding = gzip,deflate
accept-charset = windows-1251,utf-8;q=0.7,*;q=0.7
keep-alive = 300
content-length = 0
cookies         = === Cookies ===
Cookie JSESSIONID=13A7D0EF0EAE147355EED9BC4E585A83 ; 0 null null

======================================

the only difference from the first requst is referer = 
http://localhost/amazon/account.do.

This (and any other) HTML DOES NOT contain any immediate HTTP requests.



Reproducible: Always

Steps to Reproduce:
1. Log in to the www.amazon-on-demand.com using credentials "mgolovanov" -
 "karina65" as User ID / password.
2. Navigate through "My Account" section.
3. Observer request / response log. each GET will be repeated.

Actual Results:  
See above

Expected Results:  
NOT to send duplicated GETs

Netscape 7 and MS IE 6 behave properly, I have this duplication only with 
FireFox.

Check your page for anything that loads another URL, but has an empty URL
specified, e.g. <img src="">. The referer for the 2nd request is the same URL as
the page itself, so it is almost certainly because you have such an item on the
page (this would be a duplicate of bug 225554, and is correct behaviour).
