I missed the start of this thread, but how about generating a new id (or random bits) on every vists: on first connect client is assigned a session id, on subsequent connects, previous id is verified and a new id is generated and returned. This makes it even harder to crack. -- Simon Oliver

Do you have a sniffer example - I have an idea for a module that dynamically generates a sniffer/redirector. -- Simon Oliver

For example lynx replies with HTTP_ACCEPT text/html, text/plain, image/*, image/jpeg, text/sgml, video/mpeg, image/jpeg, image/tiff, image/x-rgb, image/png, image/x-xbitmap, image/x-xbm, image/gif, application/postscript, */*;q=0.01 But it can't render images or postscript! Your best bet is to use the HTTP_USER_AGENT header. From this you can work out what browser the client is using and marry this info with a database of browser capabilities (Microsoft provide one for use with IIS). The main problem is that a client can be modified from the "standard" install to prevent JavaScript, StyleSheets, Images, etc and there is no way to detect this server side. You can detect JavaScript at the client side and redirect to a JavaScript enabled URL or use the tag to provide alternative content. Again at the client side you can use DHTML to determine client capabilities and redirect or display alternative content accordingly but this will not work with all browsers, see: http://msdn.microsoft.com/workshop/author/clientcaps/overview.asp -- Simon Oliver

Have you tried DBD::AnyData? It's pure Perl so it might not be as fast but you never know? -- Simon Oliver
Global (to page) variables under Apache::ASP
In my httpd.conf I have set 'PerlSetVar UseStrict 1' because I always use sctict anyway and I see in the docs that this might become the default too. So I always declare my variables with my(). Suppose I have a master ASP file that includes other scripts and these other scripts need access to the variables declrared in the master - no problem. But reading through the docs it looks like turning on DynamicIncludes would save alot of memory and be generally more efficient. Indeed, it would also "protect" the variables declared in one file from another because the includes are compliled and called as seperate subs. And here lies the problem, how to declare a vaiable in the master ASP file that is also in the scope of the dynamic include? -- Simon Oliver
