Re: handling parameter in query_string with mod_rewrite

[Igor Cicimov <icicimov@xxxxxxxxx>]

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.

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?

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
