In our case, using VW 7.10.1, the problem only happens if we're using a reverse proxy (either HA Proxy or Apache). To debug the problem, I set up a development VW image running Seaside on port 7771 and HA Proxy on another server, redirecting port 80 to 7771. I then connected two sessions: one directly to the Seaside image, and one by way of the HA Proxy server. The directly connected session works fine, no limit on entered text that I can see. HA Proxy session has problems if the text entered is around 3500 (the exact number varies). </div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><br clear="none" class="yiv3915053710"></div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734">Cincom suggested putting a break into SiouX.NetHttpResponder>>createRequestFrom: which shows that jQuery callback from onInput is not being sent.</div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><br clear="none" class="yiv3915053710"></div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734">So, to isolate the problem (and get some help on this forum), I coded an example in a new Pharo 4.0 image, with Seaside 3.1. This example, however, has the same symptom as my VW + HA Proxy configuration: once the entered text is past around 3500, the onInput ajax callback no longer responds. I'm hoping someone can shed some light on this problem... I have some unhappy users. </div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><br clear="none" class="yiv3915053710"></div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734">renderContentOn: html</div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><br clear="none" class="yiv3915053710" id="yiv3915053710yui_3_16_0_1_1457784763197_7090"></div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><span class="yiv3915053710" id="yiv3915053710yui_3_16_0_1_1457784763197_7093" style="white-space:pre-wrap;"> </span>html heading: 'Text Editor'.</div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><span class="yiv3915053710" id="yiv3915053710yui_3_16_0_1_1457784763197_7096" style="white-space:pre-wrap;"> </span>html textArea</div><div class="yiv3915053710" dir="ltr" id="yiv3915053710yui_3_16_0_1_1457784763197_6734"><span class="yiv3915053710" id="yiv3915053710yui_3_16_0_1_1457784763197_7099" style="white-space:pre-wrap;"> </span>style: 'width: 820px;
