DO NOT REPLY [Bug 49741] New: REQUEST_URI should be explained
https://issues.apache.org/bugzilla/show_bug.cgi?id=49741
Summary: REQUEST_URI should be explained
Product: Apache httpd-2
Version: 2.2-HEAD
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Documentation
AssignedTo: bugs@httpd.apache.org
ReportedBy: qdinar@gmail.com
REQUEST_URI should be explained.
see http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewritecond :
(this bug is also present in older versions of documentation: 1.3, 2.0 )
REQUEST_URI
The resource requested in the HTTP request line. (In the example above,
this would be "/index.html".)
this is very buggy explanation.
by the way, there is not only documentation bug, but also mod_rewrite bug.
because:
URI means full uri from http: till #hash .
REQUEST_URI mean, by rules of english language, uri which was requested from
server, so it is usually without last #hash part and ends with query string or
file name or directory name.
but in apache httpd mod_rewrite REQUEST_URI does not mean that, instead it
means only part of uri without protocol, host, port, query string, question
mark that is immediately before query string, also without #hash part. ie it is
only part like /path/to/file or /path/to/file/ (which cannot contain unencoded
question mark..) . so it should be warned in documentation or even mod_rewrite
should use other keywords.
example configuraton part:
<VirtualHost *:80>
ServerName www2.example.com
RewriteEngine on
#RewriteCond %{REQUEST_URI} http.*
RewriteCond %{REQUEST_URI} www2
RewriteRule .* http://sayt1.example.com/ [R=301]
</VirtualHost>
if REQUEST_URI meant request uri, it would redirect when
http://www2.example.com/ is requested, but it does not, and it redirects if
http://www2.example.com/www2 is requested. http://www2.example.com/?www2 also
does not redirect.
one bad effect of this bug in mod_rewrite is that existence of question mark
that is used to mark beginning of query string cannot be detected with mod
rewrite in case of requested uri is like http://example.com/? .
