Forum OpenACS Q&A: Response to ns_returnredirect breaks with nsvhr and IE?

To sum up: it appears that your choices at this moment are
  • Make sure your form data is small enough (by using smaller names for your form elements or other methods) that you don't have this problem
  • use meta-refresh instead of returnredirect
  • implement the nssock graceful closewait in nsvhr and nsunix as needed, which would involve some AOLServer hacking
Option 1 was adequate for me. (I don't have time for option 3 right now. :)
