Hi,
I have produce a web form and a captcha script to stop spamming of the form.
The problem I have is that on the captcha page, after the correct text has been entered
the page redirects to another page. A couple of users who have been testing this in
Netsurf (current versions) have said they get a "url redirect error"
I have tested this on my A9home with Netsurf but do not receive any error message I am
therefore asking if anyone on here can test the url below to see if other people receive
the same error message.

The link above is directly to the captcha image. What should happen is after you have
correctly typed in the text and hit the verify button, the browser will return the text:
"All required fields must be completed"
This also appears to work fine in Internet Explorer 6, Firefox 2 and Opera 9.27.
Regards

Ugh. Why is is that most captchas are a) illegible and b) wholly
inaccessible to the visually impaired? I've never understood what's wrong
with simply asking a question that only a human could answer correctly
(e.g. "What colour is the sky?")
The problem I have is that on the captcha page, after the correct
text
has been entered the page redirects to another page. A couple of users
who have been testing this in Netsurf (current versions) have said they

Without more details, that's meaningless, I'm afraid. Please ask them to
report the issue on the NetSurf bug tracker, attaching the log file from
the NetSurf session in which the problem was encountered.

Ugh. Why is is that most captchas are a) illegible and
Thats the idea, after all, otherwise a simple bit of OCR would break them.
b) wholly inaccessible to the visually impaired?
Some do have an audio option for such users.

Which could easily be defeated by a speech recognition system. So instead
the text sounds like it is being shouted by someone at the back of a busy
call centre. Its about the same level of difficulty to understand as the
visual version.
One such example is the msn registration (only had a look it was mentioned
in the register register), but not much use for here as NetSurf can't get
to the registration page to try it out.
Cheers

Research shows that OCR is more effective at reading them than humans
are. Semantic CAPTCHAS are by far the most effective.

Anyhow better stop this now, way off topic.

I have the very same problem than Paul for a guestbook on a site I
maintain as well. Spam is increasing now and I have to act.
My solution is a totally naive one and I'm interested to see whether my
reasoning works: I think spam bots fill all text fields present, after
all they want to get their message across, the more the better. I have
now added a text field to the form with the comment "Please leave
empty!" which I enforce.
I did this just today, so have no experience on how good it works. But
I'd be interested to hear what others think, perhaps by private email
because it's getting off-topic here, but as the topic was raised here
... please forgive me.

Ok, this has now been reported on the bug tracker with a log file. The
answer is that NetSurf is being less tolerant of junk input than other
browsers. However, the URL you're redirecting to contains spaces. These
should be percent encoded (i.e replaced with %20).
At some point in the relatively near future, I'd expect NetSurf to handle
this case. It's not an entirely trivial fix, however.
John.
