Manghi\ answered:\ ***\n\n***Massimo\ Manghi\ answered:***\n\nA\ tcl\ error\ can\ be\ handled\ setting\ up\ an\ ErrorScript.\ If\ the\ error\ is\ raised\ by\ an\ abnormal\ condition\ you\ are\ catching\ somehow\ in\ your\ code\ you\ may\ call\ 'abort_page\ <abort_code>'\ which\ will\ trigger\ the\ code\ set\ up\ in\ AbortScript.\ Within\ this\ script\ you\ can\ check\ which\ condition\ brought\ about\ the\ error\ using\ the\ 'abort_code'\ command\ that\ is\ supposed\ to\ return\ the\ <abort_code>\ you\ passed\ when\ you\ fired\ the\ exception.\n\nSee\ also\ the\ 'headers'\ and\ 'no_body'\ commands\n\nSurely\ you\ can\ design\ your\ own\ error\ page\ if\ you\ want.\ It\ should\ imply\ some\ extra\ work\ but\ greater\ flexibility\n\nDid\ you\ check\ this\ page\ about\ error\

not\ possible***\n\nApache\ will\ certainly\ return\ its\ standard\ error\ messages\ when\ an\ internal\ abnormal\ condition\ occur\ that\ cannot\ be\ handled\ by\ Rivet.\nMore\ questions\ come\ up\

Manghi\ answered:\ ***\n\n***Massimo\ Manghi\ answered:***\n\nA\ tcl\ error\ can\ be\ handled\ setting\ up\ an\ ErrorScript.\ If\ the\ error\ is\ raised\ by\ an\ abnormal\ condition\ you\ are\ catching\ somehow\ in\ your\ code\ you\ may\ call\ 'abort_page\ <abort_code>'\ which\ will\ trigger\ the\ code\ set\ up\ in\ AbortScript.\ Within\ this\ script\ you\ can\ check\ which\ condition\ brought\ about\ the\ error\ using\ the\ 'abort_code'\ command\ that\ is\ supposed\ to\ return\ the\ <abort_code>\ you\ passed\ when\ you\ fired\ the\ exception.\n\nSee\ also\ the\ 'headers'\ and\ 'no_body'\ commands\n\nSurely\ you\ can\ design\ your\ own\ error\ page\ if\ you\ want.\ It\ should\ imply\ some\ extra\ work\ but\ greater\ flexibility\n\nDid\ you\ check\ this\ page\ about\ error\ customization\ in\ Apache?\n\nhttp://httpd.apache.org/docs/2.0/custom-error.html\n\n***\ George\ Petasis\ asked\ how\ to\ use\ the\ standard\ Apache\ error\ page\ ***\n\n***George\ Petasis\ asked\ how\ to\ use\ the\ standard\ Apache\ error\ page***\nIs\ this\ possible?\ \n\n***\ Massimo\ answered\ that\ this\ is\ propably\ not\ possible\ ***\n\n***Massimo\ answered\ that\ this\ is\ propably\ not\ possible***\n\nApache\ will\ certainly\ return\ its\ standard\ error\ messages\ when\ an\ internal\ abnormal\ condition\ occur\ that\ cannot\ be\ handled\ by\ Rivet.\nMore\ questions\ come\ up\ to\ my\ mind\ related\ to\ the\ error\ handling\ and\ Rivet\ interaction\ with\ other\ Apache\ components.\n\n***\ Harald\ Oehlmann\ wrote,\ why\ you\ need\ your\ own\ error\ page\ ***\n\n***Harald\
