             long clientLastModified = httpRequest.getDateHeader("If-Modified-Since"); // will return -1 if no header...
 
-            if (clientLastModified >= respContent.getLastModified()) {
+            if (( clientLastModified != -1 ) && ( clientLastModified >= respContent.getLastModified())) { 
                 ((HttpServletResponse) response).setStatus(HttpServletResponse.SC_NOT_MODIFIED);
                 return;
             }
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
