[squid-dev] [PATCH] url_rewrite_timeout directive

[Tsantilas Christos]

This is a new patch for url_rewrite_timeout feature.

Changes over the last patch:
    - The tools/helper-mux/helper-mux fixed to work with the new helpers 
request-id.
    - Now there is a limit on request retries, it is hardcoded to 2 retries.
    - The retrying request with BH replies on storeID and redrector 
helpers is nor handled inside helpers.cc code.
    - other minor polishing changes

I did not remove the on_timeout option from url_rewrite_timeout 
directive. Although it can be "emulated" using the 
use_configured_response option I believe it is a clearer configuration 
method. The "use_configured_response" looks more than a trick and I am 
sure in 1-2 years, even me I develop the patch I will forget that exist 
a such configuration option.

I must note again that the default behaviour of current helpers 
configuration, should not change with this patch.

I hope it is OK.

Regards,
    Christos
