llHTTPRequest Failure

[Void Mysterious]

Hello,

Im getting HTTP error 499 in my script when using llHTTPRequest. This happens when the server im making the requests to only accepts HTTPS, if its HTTP it works fine.

Anyone encountered this?

Thanks!

I "think" this was brought up yestreday at the server UG:

Idk if the solution is needed for external servers to accept https-in from LL servers or if it's only for LL servers to accept https-in from external servers or both.

That usually means that the remote server is not reachable (not responding). Check to see whether the server is receiving your request.

Hello Oz,

Yes, the server is reachable, when i force all traffic to use HTTPS it fails, if i allow HTTP it works fine.

Thank you.

Not sure I understand what you're saying there ... it is not true that if the server responds to http that it will always respond to https. Have you looked at the server logs to see that it is getting the request and thinks it's responding?

Let me try to explain with a bit more of detail.

If i set my webserver to accept only HTTPS by changing the virtualhost using:

RewriteEngine on
RewriteCond %{SERVER_NAME} =(DOMAIN REMOVED) [OR]
RewriteCond %{SERVER_NAME} =(DOMAIN REMOVED)
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

then the lsl scripts fails with error 499.

From the logs i see this

With the virtuahost modification

Without the virtualhost modification

What you did was create a redirect. There's a much simpler way to do that; see the documentation for the RedirectSSL directive.

If your request was a GET (you didn't say), your request might have worked (your redirect did not include any query string), but it won't work for any other method; see the wiki:

While the HTTP status code from the server is provided to the script, redirect codes such as 302 will result in the redirect being automatically and transparently followed ONLY IF the HTTP_METHOD is GET

It's also possible that the redirect you created was not to a valid url; impossible to say without specific detail or a complete log.

Thanks for the reply.

I kind of figured it out.

When using the URL https://www.example.com (Not the real domain) it fails, however if i use https://example.com it works fine, so i guess its some configuration issue on the webserver.
