    hi

    im creating a website with lots of different components eg blog/groups/forums etc - all these will be custom components
    however i want all urls to be sef which i can do no problems and i can also cache the sef link creation process (which requires a db call every time the link is displayed)
    however my question is around performance - here are my two scenarios

    save all urls in one db and cache the call to that db - (problem here is even though its cached if the db grows to thounsands + thounsands of entries even the fact that the link construction call will be called for exampel once an hour) - might those calls be very very inefficient ??

    other option is how i have done it up until now- on calling the link creation function - call the related component table , for example call for the title for the related blog and create the url from that - this process only calls to the blog table which will not have thousands and thousands of entries


    question : would the performance on the first process really be that bad?


    tnx

    why do you have to do the catching? can you not just use .htaccess to rewrite url's?

    cos i want them fully sef friendly - ie if the title of the blog is 'I took my dog for a walk in dublin' then the url will be

    I_took_my_dog_for_a_walk_in_dublin.html

    not too sure htaccess can do that ???

    that's exactly what you can do with rewrite url using .htacces

    have a look at this forum url:
    http://www.irishwebmasterforum.com/coding-help/1908-php-image-display-problem.html

    the tread is called "php images display problem"

    Caching is a good idea, as it saves on server and DB load

    The way he plans it the server will choke once an hour.

    Concentrate on getting mod_rewrite working first. It sounds to me like the caching was just a happy side effect of your sef urls, if you still need it let us know.

    I use http://www.ilovejackdaniels.com/mod_rewrite_cheat_sheet.png on a regular basis.
