Hey, I have deployed a lisp web site app. :) It runs pretty nicely. I am using CMUCL 19c and TBNL 0.9.10. Some of the dynamic pages service 45pages/sec at concurrency of 1000 (ab benchmark). thanks Edi for TBNL and the CMUCL folks for CMUCL. I need now to customize some things. I need to desperately get rid of the Internal Server Error page. If someone types in a url part of which triggers a prefix dispatcher then we get this simple "Internal Server Error" page with a info string at the bottom. I need to change both of these. Any pointers on how to do these things? I redefined the tbnl::tbnl-info-string in my source. Now I get my output string AND the original tbnl string. thanks, -- quasi Utopia Unlimited!
