When the pseudo-elliptic integration request:   
      
   \begin{axiom}   
   )set output tex off   
   )set output algebra on   
   setSimplifyDenomsFlag(true)   
   integrate((x - sqrt(a^2 + 1) - a)/((x + sqrt(a^2 + 1) - a)*sqrt((x -   
   a)*(x^2 + 1))), x)   
   )set output algebra off   
   )set output tex on   
   \end{axiom}   
      
   is entered in the grey box at the bottom of the webpage:   
      
      
      
   and then the "Preview" button hit, the following error message is   
   returned after about five minutes:   
      
   - - -   
      
   Proxy Error   
      
   The proxy server received an invalid response from an upstream server.   
   The proxy server could not handle the request POST /FriCASIntegration.

   Everything works fine, however, when the parameter a in the integrand is   
   set to 3/4.
