[users@httpd] Mod-Proxy and Mod-Headers

Hello,

I had a question about Mod-Proxy and Mod_headers

1) Is it possible to take a values that are on a query string and pass them
as headers? If so how?
For example, if I have:

http://host/myap?userid=abc&role=myrole
I would like to take the values in the query string and pass them as headers
to the app that I am proying to

2) I would like to pass the above headers or query string parameters on
every request.
How can I do this? Is there a way to put these values in session have have
them passed as headers every time?

If there is a better appraoch for the above, please let me know.

thanks in advance for your help
suneet

Hi mate,

Try something like this for the example you gave
http://host/myapp?userid=abc&role=myrole:

RewriteEngine on
Options +FollowSymLinks <http://host/myapp?userid=abc&role=myrole>
RewriteCond QUERY_STRING userid=(.*)&role=(.*)
RewriteRule ^/myapp$ [E=var1:%1,var2:%2]

RequestHeader append userid var1
RequestHeader append role var2

This is untested and not sure about the correct syntax in the
[E=var1:%1,var2:%2] flag, ie do you need coma or ; between the vars etc, but
thats the general idea.

Cheers,
Igor

Thanks Igor.

Would you be able to point me to an example? I dont fully understand how I
can configure this to take a parameter of the query string and then set a
variable as a header.

thanks for your help

Use mod_rewrite to set variable and then set that var as header.
