132985 - POST submission with only submit button fails

Status: VERIFIED DUPLICATE of bug 129333

(Core :: DOM: Core & HTML, defect)

Description

[George Lund]

Submitting a form using the POST method, that only contains a submit button,
fails with the following error message:

request#no_content_length

As far as I know such a form is allowed; the form works fine in Internet Explorer.

reporter: wich build are you using?

wfm 2002020415 on linux

Comment 2

[Morten Nilsen]

WFM on linux too, if this is indeed a bug, it seems to be a windows-specific one.
I do suspect that this might be an issue with the server side of things.

Reporter: can you supply a testcase?

I created a php script which submitted to itself, and that worked regardless
of name/value on the submit or lack thereof.

George, which build are you using?

Comment 5

[George Lund]

Sorry to have been so long in repsonding; my Hotmail account was having problems.

To respond to the questions: I thought Bugzilla included details of the build I
was using automatically, sorry: 0.9.9 anyway.

The URL given above is the test case, and the response that is received upon
pressing the submit button is "Invalid Request". Here it is again:
<http://lundbooks.co.uk/test.php>

However I am beginning to think this may be a problem with our web server rather
than Mozilla. Of course I would be grateful if anyone could let me know if that
is the case - and what to do about it! Thing is - it does work fine in IE.

Thanks

George, you're going to have to provide more information on steps to reproduce 
and especially on how to tell a successful submission from a failed one.  When 
I submit with a current Linux trunk build I get no error message but just the 
test.php page again.

Well if this can't be pinned down then so be it. It could be something peculiar
to our connection (tho' I did try with two different ISPs and via a proxy
server). The full message I get is:

request#no_content_length
-------
Description: Unable to process request for URL"http://lundbooks.co.uk/test.php".
-------

If I use a proxy server I get that proxy server's custom error response,
indicating that Mozilla sent an "invalid request". As I say, in IE there's no
error message, the page is just reloaded as you would expect (and as you seem to
get in Mozilla). We run Windows 2000. Sorry I can't think of anything else that
might explain it!

the form wfm with a cvs build from today on win2k. I get the same results in 
mozilla as I do in IE6.

Comment 9

[Boris Zbarsky [:bzbarsky]]

Ah.  Of course.  "request#no_content_length" means the request has no
content-length header....

Duplicate of "Submitting form creates bad request according to squid" (we were
not putting content-length on some requests, fixed March 12).
