hello,
i am wondering what the best approach is to solve the following:
i have a working website (apache 2 and mod_websh) with file-based
server-side sessions. it produces URLs like
http://192.168.10.21/service.ws3?XDp6dPEFi3xtaYvFCPSjJVslyQ7vJiVQrl80QgWn0f0NBH2DmH
all fine. now... to interface with an external card-billing website, the
user's browser is sent to an exernal billing server; a URL is passed along,
which the billing server later embeds into its page upon completion of the
payment; it is used to send the customer back to my websh based site. the
billing server... attaches parameters to this URL; for example:
http://www.7wire.com/returnpage.html?DATA=%3CIDP+MSGTYPE%3D%22PayConfirm%22+KEYID%3D%221%2D0%22+ID%3D%22EYzzx3ArSOQpSAWC6fxQAvx40000%22+TOKEN%3D%
22%28unused%29%22+VTVERIFY%3D%22%28obsolete%29%22+AMOUNT%3D%22555%22+CURRENCY%3D%22CHF%22+PROVIDERID%3D%2290%22+PROVIDERNAME%3D%22Safer
pay+Test+Card%22+ACCOUNTID%3D%2299999%2D94913159%22+ECI%3D%222%22+CCCOUNTRY%3D%22XX%22%2F%3E&SIGNATURE=51eb5c374e163539f8aff5cdb7249db6
aec8165738f1ec3e44ac73e3de9c530b8ffff2d55f90369d176538e4d0e3067e4635d531965b9c4b63089be50fd4ffff
i am wondering about what is the best way to marry the two: i'd like to
keep the encrypted data from the websh environment, but need to gather the
ID parameter from the billing server's reply. i wanted to essentially chain
the two or embed the websh data like the SIGNATURE, but this would require
pre-processing the querystring before it is dispatched under websh. from
what i've seen from the sources, the url is not available to the tcl
environment for manipulation before dispatching. i would either add this or
process in C, but there may be a better way...??
