== Environmental variables ==
Proxy support in general is handled by most Unix programs by setting environment variables. These variables are:
*<code>HTTP_PROXY</code>: hostname or IP address of proxy user
*<code>HTTP_PROXY_PORT</code>: port number the proxy server is listening on
*<code>HTTP_PROXY_TYPE</code>: type of proxy, valid values:
**SOCKS4
**SOCKS5
**HTTP
*<code>HTTP_PROXY_USER</code>: username for proxy authentification
*<code>HTTP_PROXY_PASSWD</code>: password for proxy authentification

== Behaviour in Seon ==
If proxy support is disabled, the above variables are overwritten with empty values by all Seon binaries. In subsequent processes (like event scripts or plugins), these environment share the same variables as the parent processes have. If you need special variable values for the above listed variables, you have to take care about them in your use cases.

If you have [[Seon_Core_configuration#Use_proxy.3F|enabled proxy support]] in Seon and [[Seon_Core_configuration#Use_user_settings.2Fenvironment_variables.3F|enabled usage of these special environmental variables]], Seon doesn't change these values and doesn't use other definitions for HTTP proxy definitions.

If you have [[Seon_Core_configuration#Use_proxy.3F|enabled proxy support]] in Seon and [[Seon_Core_configuration#Use_user_settings.2Fenvironment_variables.3F|disabled usage of these special environmental variables]], Seon will change eventually set environment variables by setting them to the defined values in the Seon definition, so it overwrites these variables in all processes.

The URLs needed are dynamic, so there is no absolute definite list of URLs for which Seon must be allowed to access these ressources.

 Proxy support in general is handled by most Unix programs by setting a special environment variable "<code>http_proxy</code>". This variable is build with some parts of information needed. The syntax for this variable is:
