h2_proxy_session.patch
Hi
I found bug in http2 proxy. Content-Type header is not set correctly if served
file name match with mime.types
With simple http proxy it's handle via `mod_proxy_http.c:1302-1304`
I can reproduce this bug with a front httpd proxying to an other httpd that
serving php files.
Here my test case
First httpd server: `100-httpd-proxy.conf`
> <VirtualHost *:${HTTP_PORT}>
> ServerName localhost
>
> ProxyPreserveHost On
>
> # I use h2c instead h2 for test case for convenient but bug append also
> with h2
> # I use docker containers, so httpd DNS point to second server
> ProxyPass /h2c/ h2c://httpd/
> ProxyPassReverse /h2c/ http://httpd/
>
> ProxyPass /h11/ http://httpd/
> ProxyPassReverse /h11/ http://httpd/
> </VirtualHost>
Second httpd server: `100-httpd.conf`
> <VirtualHost *:${HTTP_PORT}>
> ServerName localhost
>
> DocumentRoot /srv/httpd/app
>
> <Directory /srv/httpd/app>
> Require all granted
> </Directory>
>
> ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://php:9000/srv/httpd/app/$1
> </VirtualHost>
`/srv/httpd/app/info.php` and `/srv/httpd/app/info.conf.php`
> <?php
> phpinfo();
> % curl -w "%{content_type}\n" -so /dev/null 'http://localhost/h11/info.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null
> 'http://localhost/h11/info.conf.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null 'http://localhost/h2c/info.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null
> 'http://localhost/h2c/info.conf.php'
>> text/plain
I patch `h2_proxy_session.c` to have same behaviours as http1.1 proxy
After rebuild with patch I have
> % curl -w "%{content_type}\n" -so /dev/null 'http://localhost/h11/info.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null
> 'http://localhost/h11/info.conf.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null 'http://localhost/h2c/info.php'
>> text/html; charset=UTF-8
> % curl -w "%{content_type}\n" -so /dev/null
> 'http://localhost/h2c/info.conf.php'
>> text/html; charset=UTF-8
