Hi list,
I'm currently having some trouble with Apache 2.2.25 running in
conjunction with PHP 5.4.4. It's running a blog software (b2evolution).
Please don't judge me, it's not my blog :-) Anyways, permalinks to the
blog previously looked like this:
http://www.myserver.com/blog5.php/this-is-a-permalink
Now I've changed around the server config so they're more generic
(ultimately I want to move away from PHP). Now they look like this:
http://www.myserver.com/blog/this-is-a-permalink
To get this working, I had issued a mod_redirect directive in the
Directory section for the relevant vhost:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} ^/blog/[-a-zA-Z0-9]+$
RewriteRule ^blog/([-a-zA-Z0-9]+)$ blog/index.php/$1 [L,QSA]
Now when an access occurs to /blog/this-is-a-permalink it works nicely
and this is the mod_redirect log output I get:
strip per-dir prefix: /var/www/myserver.com/blog/this-is-a-permalink ->
blog/this-is-a-permalink
applying pattern '^blog/([-a-zA-Z0-9]+)$' to uri 'blog/this-is-a-permalink'
rewrite 'blog/this-is-a-permalink' -> 'blog/index.php/this-is-a-permalink'
add per-dir prefix: blog/index.php/this-is-a-permalink ->
/var/www/myserver.com/blog/index.php/this-is-a-permalink
strip document_root prefix:
/var/www/myserver.com/blog/index.php/this-is-a-permalink ->
/blog/index.php/this-is-a-permalink
internal redirect with /blog/index.php/this-is-a-permalink [INTERNAL
REDIRECT]
add path info postfix: /var/www/myserver.com/blog/index.php ->
/var/www/myserver.com/blog/index.php/this-is-a-permalink
strip per-dir prefix:
/var/www/myserver.com/blog/index.php/this-is-a-permalink ->
blog/index.php/this-is-a-permalink
applying pattern '^blog/([-a-zA-Z0-9]+)$' to uri
'blog/index.php/this-is-a-permalink'
pass through /var/www/myserver.com/blog/index.php
strip per-dir prefix: /var/www/myserver.com/this-is-a-permalink ->
this-is-a-permalink
applying pattern '^blog/([-a-zA-Z0-9]+)$' to uri 'this-is-a-permalink'
pass through /var/www/myserver.com/this-is-a-permalink
This is how it looks on the client side:
> GET /blog/this-is-a-permalink HTTP/1.1
> User-Agent: curl/7.31.0
> Host: www.myserver.com
> Accept: */*
>

For compatibility, however, I'd like to also support a redirection to
the old style links (for people who still have bookmarks). Therefore I
introduced the analogous commands:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} ^/blog5.php/[-a-zA-Z0-9]+$
RewriteRule ^blog5.php/([-a-zA-Z0-9]+)$ blog/index.php/$1 [L,QSA]
This isn't working at all, however:
add path info postfix: /var/www/myserver.com/blog5.php ->
/var/www/myserver.com/blog5.php/this-is-a-permalink
strip per-dir prefix:
/var/www/myserver.com/blog5.php/this-is-a-permalink ->
blog5.php/this-is-a-permalink
applying pattern '^blog5.php/([-a-zA-Z0-9]+)$' to uri
'blog5.php/this-is-a-permalink'
rewrite 'blog5.php/this-is-a-permalink' ->
'blog/index.php/this-is-a-permalink'
add per-dir prefix: blog/index.php/this-is-a-permalink ->
/var/www/myserver.com/blog/index.php/this-is-a-permalink
strip document_root prefix:
/var/www/myserver.com/blog/index.php/this-is-a-permalink ->
/blog/index.php/this-is-a-permalink
internal redirect with /blog/index.php/this-is-a-permalink [INTERNAL
REDIRECT]
add path info postfix: /var/www/myserver.com/blog/index.php ->

strip per-dir prefix:

'blog/index.php/this-is-a-permalink'
add path info postfix: /var/www/myserver.com/blog/index.php ->

strip per-dir prefix:
/var/www/myserver.com/blog/index.php/this-is-a-permalink ->
blog/index.php/this-is-a-permalink
applying pattern '^blog/([-a-zA-Z0-9]+)$' to uri
'blog/index.php/this-is-a-permalink'
pass through /var/www/myserver.com/blog/index.php
strip per-dir prefix: /var/www/myserver.com/this-is-a-permalink ->
this-is-a-permalink
applying pattern '^blog5.php/([-a-zA-Z0-9]+)$' to uri 'this-is-a-permalink'
strip per-dir prefix: /var/www/myserver.com/this-is-a-permalink ->
this-is-a-permalink
applying pattern '^blog/([-a-zA-Z0-9]+)$' to uri 'this-is-a-permalink'
pass through /var/www/myserver.com/this-is-a-permalink
And on the client side:

> User-Agent: curl/7.31.0
> Host: www.myserver.com
> Accept: */*
>

So ultimately I think the initial redirect is working (at one point it
actually says blog/index.php/this-is-a-permalink) and it's passing it
through the blog's index.php, but then apparently some weird additional
redirection happens which ultimately sends it to /this-is-a-permalink
(which is a 404 and therefore apparently translated into a 301 to the
blogs default page).
I must admit that this really puzzles me, but I am really also not too
sure that I'm using mod_redirect appropriately. If you know what's wrong
and could help me I'd be forever grateful. Thank you very much in advance,
Best regards,
Johannes
