Description:
Apache module to decode data submitted from Web forms (development files)
mod_form is an Apache module to decode data submitted from Web forms. The decoded data is made available to other Apache modules through two optional functions exported by mod_form with APR_DECLARE_OPTIONAL_FN. . It deals with both GET and POST methods where the data are encoded using the default content type application/x-www-form-urlencoded. . This package contains the development files for Apache modules that wish to rely on mod_form.
