- Keys supported:
-
- URI______:

- HTTP_HOST = [host][:[port]] = 192.168.1.4:8080
- SCRIPT_NAME = [path_script]++ = /typo3/32/temp/phpcheck/index.php // NOTICE THAT SCRIPT_NAME will return the php-script name ALSO. [path_script] may not do that (eg. '/somedir/' may result in SCRIPT_NAME '/somedir/index.php')!
- PATH_INFO = [path_info] = /arg1/arg2/arg3/
- QUERY_STRING = [query] = arg1,arg2,arg3&p1=parameter1&p2[key]=value
- HTTP_REFERER = [scheme]://[host][:[port]][path] = http://192.168.1.4:8080/typo3/32/temp/phpcheck/index.php/arg1/arg2/arg3/?arg1,arg2,arg3&p1=parameter1&p2[key]=value
- (Notice: NO username/password + NO fragment)
-
- CLIENT____:
- REMOTE_ADDR = (client IP)
- REMOTE_HOST = (client host)
- HTTP_USER_AGENT = (client user agent)
- HTTP_ACCEPT_LANGUAGE = (client accept language)
-
- SERVER____:
- SCRIPT_FILENAME = Absolute filename of script (Differs between windows/unix). On windows 'C:\\blabla\\blabl\\' will be converted to 'C:/blabla/blabl/'
-
- Special extras:
- TYPO3_HOST_ONLY = [host] = 192.168.1.4
- TYPO3_PORT = [port] = 8080 (blank if 80, taken from host value)
- TYPO3_REQUEST_HOST = [scheme]://[host][:[port]]
- TYPO3_REQUEST_URL = [scheme]://[host][:[port]][path]?[query] (sheme will by default be 'http' until we can detect if it's https -
- TYPO3_REQUEST_SCRIPT = [scheme]://[host][:[port]][path_script]
- TYPO3_REQUEST_DIR = [scheme]://[host][:[port]][path_dir]
- TYPO3_SITE_URL = [scheme]://[host][:[port]][path_dir] of the TYPO3 website
- TYPO3_DOCUMENT_ROOT = Absolute path of root of documents: TYPO3_DOCUMENT_ROOT.SCRIPT_NAME = SCRIPT_FILENAME (typically)
-
- Notice: [fragment] is apparently NEVER available to the script!
-
-
- Testing suggestions:
- - Output all the values.
- - In the script, make a link to the script it self, maybe add some parameters and click the link a few times so HTTP_REFERER is seen
- - ALSO TRY the script from the ROOT of a site (like 'http://www.mytest.com/' and not 'http://www.mytest.com/test/' !!)
