[users@httpd] handling parameter in query_string with mod_rewrite
Hi All,
I would need some help with mod_rewrite :-( .
What I would need is to add an header to the response if the request
contains a URL parameter and the value of that parameter should be used
in that header.
Just to clarify, if the url is:
/download/files/1ytreefecsw?filename=myfile.txt
I would like to return this file /download/files/1ytreefecsw setting in
the response "Content-disposition" header with value myfile.txt:
"Content-disposition: attachment; filename=myfile.txt
I was able to do this thing checking a request header using:
SetEnvIf x-filename "^(.+)$" FILENAME=$1
Header set "Content-disposition" "attachment;
filename=%{FILENAME}e" env=FILENAME
but now i need to do similar thing using a parameter.
I understand that there is not a simple way to access to the
query_string and actually this is not possible using SetEnvIf and it
seems the right way is using mod_rewrite .... but i don't find the
solution.
At the moment i'm trying something like:
RewriteEngine on
RewriteRule ^(.*)filename=(.*)$ $1 [E=FILENAME:$2]
Header set "Content-disposition" "attachment;
filename=%{FILENAME}e" env=FILENAME
but it doesn't work :-((
Could you help me ?
Thanks
ste

Hi Igor,
maybe my issue was not fully clear but your suggestion puts me on the
right way .... thanks a lot !!
What I'm using now (and it seems working) is:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)[\&|\?]*filename=([\w|\d|\.|\%|
]*)[\&]*(.*)$
RewriteRule .* - [E=FILENAME:%2]
Header set "Content-disposition" "attachment;
filename=%{FILENAME}e" env=FILENAME
UnsetEnv FILENAME
The main difference is that myfile.txt was just an example, ie, I
should be able to handle any value and that parameter in any position.
For instance:
/download/files/1ytreefecsw?filename=first.txt
/download/files/1ytreefecsw?param1=value1&filename=second.txt¶m3=value3

Sorry this should have been like this actually
RewriteEngine On
RewriteCond %{QUERY_STRING} ^filename=(myfile.txt)$
RewriteRule .* - [E=FILENAME:%1]
to set the FILENAME variable to myfile.txt value.

Re: [users@httpd] handling parameter in query_string with mod_rewrite

RewriteRule doesn't work with the query part or the URI thus will not work
in your case. You need to try RewriteCond directive combined with
RewriteRule. Something like this maybe?
RewriteEngine On
RewriteCond %{QUERY_STRING} ^(filename=myfile.txt)$
RewriteRule .* - [E=FILENAME:%1]
Header set "Content-disposition" "attachment; filename=%{FILENAME}e"
env=FILENAME
I'm not sure though about the effect of the Header set directive, is it
going to have a global effect afterwords or not?
