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

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?

RewriteRule doesn't work with the query part or the URI thus will not w=
ork in your case. You need to try RewriteCond directive combined with Rewri=
teRule. Something like this maybe?

RewriteEngine On
RewriteCond %=
{QUERY_STRING} ^(filename=3Dmyfile.txt)$

RewriteRule =A0 .*=A0 - [E=3DFILENAME:%1]
Header set "Content-dispo=
sition" "attachment; filename=3D%{FILENAME}e" env=3DFILENAME=


I'm not sure though about the effect of the Header set directiv=
e, is it going to have a global effect afterwords or not?

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.

Sorry this should have been like this actually

RewriteEngine On
R=
ewriteCond %{QUERY_STRING} ^filename=3D(myfile.txt)$

RewriteRule =A0 .*=A0 - [E=3DFILENAME:%1]

to set the FILENAME variab=

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.tx t¶m3=value3

Hi Igor,

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=secon d.txt&param3=value3
