This question isn't so much about Perl.
Let me know if I should take them elsewhere.
But it begins with PERL. I'm running ActiveState5.10 on my Windows XP laptop. Running a Perl program that is attempting to HTTP POST to a file at my website. When posting to a x.txt file with 777 I get:

405 Method Not Allowed
Method Not Allowed
The requested method POST is not allowed for the URL /x.txt.

Seemed clear to me....So I open a question/problem with my ISP about POSTing. And they reply that a Perl program can only POST to a file that ends with .pl. I replied that I didn't think the type of code that issued the POST was relevant but gave their suggestion a try.
That round cause some errors that looked as if the file being posted to was being executed as a Perl program. ISP then advised me to update my permissions to 755. Which ended in the message below:

C:\Perl\perlscripts>put05.pl
HTTP/1.1 500 Internal Server Error
Connection: close

It makes since that not just anyone can POST to any file on a website and so I suspect it's more of a permission/security issue. But just wanted to make sure I had a good overall understanding. Must Perl only POST to .pl files? Anyone have a area about POSTing that I should look at first?
Thanks Monks!
