Summary

0000106: if-modified-since with IE 6

Description

RSN-97
(rep by Anupam Bagchi)

We recently tried to use gzip filter for our product using Resin 3.0.12 and found a problem with IE 6. We have tracked it down to the code and here is the diagnosis.

In Resin 3.0.12, com.caucho.servlets.FileServlet, line 0000257:

    String lastModified = cache.getLastModifiedString();

    if (ifMatch == null) {
      String ifModified = req.getHeader("If-Modified-Since");

      if (ifModified != null && ifModified.equals(lastModified)) {
        if (etag != null)
          res.addHeader("ETag", etag);
        res.sendError(res.SC_NOT_MODIFIED);
        return;
      }
    }

The problem with IE 6 is that is has "; length=xxx" at the end of the ifModified string and Resin needs to strip out this information before comparing it to lastModified.

Will appreciate if you can include this fix in the next Resin release.
