Well, I'm sorry if I said something stupid, especially if this hurt your
feelings. It may be my English and the fact that I didn't think much on
how to say that politely... Curl (libcurl) has helped me a lot and I thank
you Daniel and other guys that helped at this project. It was not my
intent to offense any of you. I was just trying to a report a problem, to
say that what the persons who reported that he gets the HTML code altered
is not the only one and that I was facing the same problem.

Well, it may be my fault, but in my case, something really strange do
happen. I got the HTML code into a perl array and print it out to a
file. When checking the file, an extra space appears there.

I certainly cannot... I can only observe that the libcurl I am/was using
may have some problems, problems that another user has reported too.

Well, I wasn't asking for support here, because it wasn't that urgent. I
was only reporting a problem that I am facing. If I wanted help, I would
have included the exact code, which I will be doing once I can use the
computer that curlib is installed (I can't include the code now, because i
can't access it, and I couldn't when I wrote the first email either),

> What did the code look like? "crashed", what does that mean?

The perl interface didn't report any errors, no warnings. The code was
working fine, but at some point the page to be downloaded didn't get
through (no, the internet access was still ok). Unfortunately, I didn't
use the curlib verbose option.. I only stoped the script and started if
again, from the page that I couldn't receive.

There was no error message, no warning message.

And you did that for me too... which I tahnk you for.

I am aware of this too....

If I wanted an urgent support, I mean if I wanted your help, I would have
included more details, including the code, which I will be doing when I
really need help. Yes, I think that happened to me was pretty strange. And
believe me, before I write to the list asking for help, I always try to
solve the problem by myself, trying it for more than one time and
researching by myself. I did this when I had that space problem and the
other problem when trying to download the HTML pages. And I did look
through the perl code at least 10 times, carrefully, to see if it's
actually my fault... but I coudln't find anything that I did (or
didn't) to cause these problems to appear... the again, it may be my
fault, but since similar things happened to another user, I wanted to
report the problems I have, not (only) because I wanna be helped, but
also because if there's a problem in libcurl, we have to find it together
so that the other users of libcurl won't experience these problems

And again, if I offensed you in any way, I apologize.
