Hi !

I'm curretly trying to make httpclient classes working for connecting to an HTTPS page.

I have adapted the test_http.php that is enclosed in the package to connect to http://mail.google.com/mail/feed/atom and retrieve the RSS feed.
Though I'm connecting to the internet through a proxy, it looks to be correctly configured because I can reach normal HTTP pages.

The point is that the page http://mail.google.com/mail/feed/atom redirects to https://mail.google.com/mail/feed/atom for consulting the RSS feed. Apparently, I did not configure correctly the httpclient class for connecting to any HTTPS page (I tried several). I am successfully redirected from HTTP to HTTPS page.

On any HTTPS page, here is the error I still cannot avoid :
500 Server Error
[code=PARENT_NEEDED] Unable to service this URL without parent cache.Contact your system administrator.

I could find only few information about this error.
What does it mean ? How can I fix it ? What did I miss ?

Thx 4 your help !!!

Currently you cannot connect to a SSL remote server using some non-SSL HTTP proxy. That is considered insecure because the connection between the client and the proxy is not secure.

The solution is to support the HTTP CONNECT method. However, that requires that the client knows how to dialog with proxy in SSL after that connection is establish.

I would need to study the subject further as most PHP versions are not able to start a SSL dialog after the connection is already established. For now I advise to try a different solution if you can.

Thanks for your answer, Manuel.

Finally, I changed my mailbox (Gmail was not compulsory, as I just need to check wether outgoing emails are correctly output from my network - there might likely be a dozen of sendmail relaies between my server's and the Internet) for a lower-secured one that alsoprovides RSS feeds.

Thus, I kept my first solution, which was an class extended from PEAR::HTTP_Client that allows HTTP redirections (HTTP Request doesn't). Overloading get and post methods made this little class supporting the proxy authentication (I found out that native HTTP_Client doesn't).

I'll likely share this tiny code on PHP Classes, once I'll get more used to this site and have some time.

Thanks again for your help !

Matthieu.

I am not sure what you mean. My HTTP protocol client supports redirections and proxy authentication. Or are you saying that PEAR classes do not support that?

Sorry for misunderstanding. I just meant that, before I find your httpclient classes on PHP classes network, I already had extended PEAR classes to almost suit my needs.
I'm sure your class can do this very well too, I just got it after I made a first solution working.
