Web SIte ACross Multiple Servers WIth Authentication

Asked by Fatlog in Apache Web Server

hi,

this is probably more of a discussion thing.
i have an application which is located on multiple servers. a complete version of the application is located on ecah server and runs away doing its thing. runs fine. no issues there. i have a website that gathers data from each server and displays it on one page. this is important. all the data has to be displayed in one loctaion. webiste is built in PHP and MySQL. Server is linux and webserver is apache there are two issues that i want to get opinions on...

1. i currently use CURL to request data from each server(data is returned as xml) and then combine this data together to form the page for the user. is this the best way to share data between the servers? or would it be better/more advisable to just connect directly to each servers version of MySQL and query it for the data directly instead of requesting and generating XML. this is more a design consideration than functionality. if you were building an application across multiple servers what approach would you take? the servers are all located within the same providers data centre and have private net.

2. my second issue is authentication. i currently employ a simple cookie system for authenticating users. i want to move to using digest authentication across all my sub-domains so a user can move from one server to the next without being asked for username/password again. this works fine in practice(got around the MS IE problems with GET variables as well). only problem is none of my current CURL requests between servers work when i use digest. if i were to stick with the CURL setup is there anyway to allow page requests that originate from the server/domain to be bypass the authentication check?

any and all commenst are welcome.

thanks
